Python is a great language for creating web applications. But not all hosts offer it. And not all host support it as you might wish. This article will introduce you to Python and show you how to find the right Python host.
What is Python?
Python is an object-oriented programming language devised in the late 1980s. Now on version 3, it’s still popular with programmers.
Named after Monty Python’s Flying Circus, a 1970s BBC TV comedy series, Python’s creators designed the language to be enjoyable for programmers to use.
The variables “foo” and “bar” are often used in documentation of programming languages, but in Python, the same demonstrations are generally written with variables named “spam,” “ham” and “eggs.”

Mixed Programming Paradigms
Python is ideal for those who like to mix an object-oriented approach with structured programming. It’s also designed to be easily read and understood by novices thanks to a very simple stylistic form and grammar.
The code is intentionally written very clearly and concisely and is easy for inexperienced programmers to review and change. Where many languages use punctuation, Python leans towards using English words, making any given file less cluttered visually. It is also clearly indented when written to make the code easy to scan.
Python’s functionality can be extended with add-on functions written in C or C+, and it can also be used as a command language with C.
Code can also be run from within a Java application, allowing Java variables to be called from within Python and re-used.
Python Is Easy to Learn
Compared to languages that appear impenetrable to the novice, Python is considered to be easier to learn, and its cross-platform compatibility is one of its major benefits.
It can be coded in the Terminal app on macOS, but is also often used for security applications, or web applications running on a Unix or Linux server.
The language is employed by YouTube, Google, and NASA, as well as CERN, the home of the Large Hadron Collider. CERN use Python to decode data from Atlas, one of the LHC sensors. The staff also host Python conferences and uses Python extensively in their physics and computing labs.
If you’re venturing into coding with Python and creating a Python application for the first time, there is a wealth of support available.
Python is used by some of the biggest sites on the internet, despite having a reputation for being “slow” compared to other languages, and there are numerous web resources, tutorials, online classes, and books which will get you started quickly.
Take Care in Hosting
There are lots of options if you’re looking for Python hosting, but some care is needed.
Make sure you select the right plan and really drill into the details of your preferred host’s Python offering before you sign up for a long-term hosting commitment.
Python Is Ideal For Web Apps
Python is extremely adaptable, and there aren’t many limits to what it can do.
Why Python Is So Good
It’s ideal for web development because it’s quick to write (there’s a lot of built-in support for things like HTTP and MySQL database integrations) yet can be used in advanced, sophisticated applications.
All kinds of companies, from BitTorrent to YouTube, have used (or currently use) Python, and it plays a part in processing some of the most cutting-edge scientific data on Earth at NASA and CERN. Its versatility and simplicity make it an ideal choice for web apps as well.
Easy to learn Python and write code
Runs on different server operating system
Used by by big companies like YouTube, Google, NASA, CERN
Language has a lot of support
Lots of frameworks available
Easy to develop Python applications
Furthermore, the abundance of well-written Python web frameworks, such as Django, TurboGears, web2py, Flask (which is technically a microframework), and Pyramid, means that you can code web applications without worrying about how to handle low-level details, such as protocols, sockets, or process and thread management.
Such server-side requires explicit support, so if you opt to use a framework, be sure that your web host supports it as well.
If you’re new to running Python on the web, you might want to check that your host offers Python tech support for free — just in case you need a hand getting things set up in the beginning.
Warning: Some Hosts Don’t Offer Python
Naturally, you should ensure that Python is installed on your chosen web host’s servers and that it can handle your any file you upload before you sign up: some hosts, particularly those who offer shared hosting, don’t offer it at all.
Python Can Slow Down Servers
That’s usually because inexperienced programmers can slow an entire server by coding their Python app inefficiently, bringing down other customers’ sites in the process.
Malicious programmers could cause problems in a shared environment since mod_python isn’t locked down as tightly as mod_php on Apache.
Check for Frameworks Too
When looking for Python hosting, check for support for frameworks such as Flask and Django. Ascertain the version of Python and mod_python the web host is running.
Python 2 and Python 3 are quite different, and you may find the version your host has installed currently is not entirely backward-compatible. You’ll also want to dig deeper into the specifics — some web hosts limit your use of Python to selected situations only.
Check the interpreter that your host is using and make sure it’s suitable for your needs.
Some interpreters are out-dated, and requests for an upgrade may fall on deaf ears. Ensure you have shell access and that the Apache installation supports CGI and mod_wsgi, as well as anything you need for your web framework.
Check Python Modules
It’s also worth checking the host’s policy on Python modules.
Some Python web hosts are happy to install whatever you need and will do so relatively quickly — for example, within 24 hours.
Other hosts may have policies around which modules they will allow, and they will refuse to install anything that’s unproven or untested.
Also, check that your host will allow you to run persistent processes (sometimes called ‘long-running processes’) on its servers, particularly if you have your heart set on a cheaper plan, such as a shared hosting plan.
Many hosts don’t allow such processes because they are, by nature, resource hogs. Even if you have a shared hosting plan offering unlimited resources, your web host may consider your apps more appropriate for a VPS plan or dedicated server and terminate your contract accordingly.
If you need to run persistent processes, you may be best off investing in a virtual private server (VPS) instead, or you may just want to bite the bullet and get a dedicate server – an expensive option, but one which will allow you to code whatever you like, however you like.
Dedicated Servers Require Maintanance
Be wary, however, of opting for a dedicated server if you don’t want to spend time fixing things on your server that you accidentally break along the way.
Again, we want to reiterate that a virtual environment offered by a VPS plan will save you from this kind of trouble, or you might consider looking into a managed plan that supports custom coding.
Special Python Plans
If you want to exclusively code in Python or base a large amount of your coding around it, it’s best to personally email the host before signing up for a contract. They may have a special plan for Python at a reasonable cost that gives you more freedom and flexibility.
Choosing a Host
The best option for Python is a dedicated server. While it’s an expensive option, a dedicated server comes without limitations so that you can take control of your Python install.
Second Best: VPS
If you don’t want to go dedicated, you would be best off with a Virtual Private Server (VPS), rather than a shared hosting plan. In fact, most hosts won’t support Python on shared hosting, since it’s too easy for inexperienced coders to bring a server down unwittingly, and because running Python apps can be a resource drain.
Things to Remember
When choosing a web host for Python:
Make sure that your chosen package has Python support in the specs
Check the Python interpreter version, since a host may be reluctant to update an old interpreter if there’s little demand
Ascertain which modules are installed, and what the policy is regarding new modules
Check on whether you can install Python packages, which are directories of Python modules, by yourself
Make sure your host will allow you to run persistent processes; on shared hosting, this is unlikely
Check that you have shell access
Check what your options are when it comes to databases — you can expect Python scripts to play well with a MySQL database, generally speaking, but if that’s not an option, you’ll need to do a bit more digging.
If you plan to spend a lot of time working with Python, look for a host that specializes in it, rather than going for the cheapest host and hoping for the best. In the long run, you’ll find it’s far easier to pay slightly more for a host that’s supportive and keeps their Python install up to date.
Additionally, the host will expect you to run persistent processes and won’t penalize you for it. Use the host’s email support or Live Chat to ask them about Python before committing yourself to a monthly spend.

Because Python hosting is somewhat niche, we simply looked for hosts that offer full support for Python, multiple frameworks, and use of modules/packages, as well as availability of support (both in terms of tech support and online documentation) in case you run into issues with any of these items.

Other hosts we looked at, including SiteGound, iPage, and GoDaddy, all offer some support for Python, but there were either strict limitations on what could be done, or we felt that support was a mere afterthought.

Pros and Cons
Python is used by all kinds of companies and organizations, including Google, NASA, and CERN. The Large Hadron Collider (LHC) decodes its critical ATLAS data using Python. So there are many reasons to use it. But there are cons too.
It supports HTTP and MIME out of the box, so you can get up and running with your web apps written in Python faster
You can code extensions in C or C++
Python can be run from Java applications
Programmers can easily connect to databases to bring content into their projects
There are tens of thousands of pre-made, freely available packages to speed up development and potentially cut costs.
It can be difficult to spot mistakes in your file until it’s time to run the code, which makes debugging cumbersome
It can be slow, so you’ll need a speedy host to compensate
Unless you’re an experienced developer, learning Python solo is a challenge
Hosts that have Python installed may not be able to help you if you run into a technical problem — a lot of hosts stipulate that they support Python-based applications, but their support team does not cover malfunctions as a result of your code
Few hosts will provide Python support for a shared hosting plan, which means you will have to opt for the more expensive VPS hosting plan or dedicated server. As such, this is not a cheap undertaking.
Despite the fact that the Python programming language is commonly-used by entities both small and large, web hosting for websites and apps utilizing Python can be hard to find. There are lots of reasons for this, but the bottom line is that you’ll probably pay a premium to get the hosting environment you need.
Python is a free, open source programming language that was originally released in 1991.
Is Python used for developing websites?
It can be used for web development, but it has many other purposes too. Python was originally designed to help with system administration, and can now be used to make applications, analyse data, and more.
Are there any web development frameworks for Python?
Yes. The most popular Python web application frameworks are Django, Flask, Pyramid, and CubicWeb.
Why is Python popular?
Python is designed to be user-friendly and easy to learn. It’s not as widely used as PHP, but it’s well-documented, and there are lots of modules available to make coding fast and fun.
Should I learn Python to develop a website?
Building a website or web application is a huge task for a beginner.
Initially, it might be more sensible to use something like WordPress or Drupal, and then code your own plugin in PHP. That will give you a significant head-start, compared to coding something from scratch.
Remember: Python can also run slow, particularly if you plan to use v3. While a fast server can compensate for this, it might not be ideal for some purposes.
Why is Python recommended for beginners?
Python is included on Linux and Mac systems, so there’s little complexity involved in getting started. The syntax is relatively easy to read, even if you don’t know how to code, because it uses a lot of English words.
Many Python programmers begin by writing small scripts for their own computers, and then building on that knowledge to develop larger applications.
Python also includes a built-in web-server, so you can run a web app locally as you are developing it. That’s easier than installing and configuring a separate server like Apache.
Is Python available on shared hosting plans?
Sometimes, but it isn’t a standard feature by any means. If your sole purpose of buying a hosting account is to learn Python, check the fine print very carefully before you sign up.
What do I need to look for in a hosting package?
The requirements are the same whether you’re coding in Python, or you want to run a Python application by someone else.
Look for a plan that specifically mentions Python in the technical specifications; don’t assume that it’s provided, because not all hosts offer it. A VPS or a dedicated server is a safe bet.
Additionally, make sure that you have the version you need, because different versions of Python aren’t fully compatible.
If you are developing a new app, make sure you have the same version on your development machine and your production server.
Finally, look for modules and libraries that you need before you sign up. These may need to be compiled with Python, and if your host hasn’t done this, you won’t be able to use them.
Some hosts will install things on request, but others will ask you to upgrade to a VPS or dedicated server.
What is mod_python?
In basic terms, mod_python is a module within Apache that allows Python code to run on the web server. This is one of the most efficient ways to run Python.
What is a module?
A Python module is a script that allows you to complete a specific task. A package contains a bundle of modules and a file named __init__.py.
You can download packages from the PyPI repository, and your host will already have some modules installed that you can use.
However, some hosts will refuse to install modules on demand. Check the fine print in your host’s Terms of Service if this could be an issue for you.
Are there any alternatives to Python?
For writing web applications, the two most popular alternatives are PHP and Ruby. For desktop utility scripting, you could try Ruby, Perl, or Bash.
Should I use Python or Ruby for my project?
If you are a true beginner, and you just plan to develop one or two things, Ruby (with Rails) is probably a better choice than Python. If you are interested in experimenting and building your skills as a coder, go with Python from day one.
Is it easier to use PHP rather than Python?
In technical terms, Python is considered to be superior to PHP, and more suited to ‘serious’ projects. But more people learn PHP, because it’s more widely used and supported. In that sense, it can be ‘easier’ to learn.
There are also many frameworks available for PHP (including Laravel, CodeIgniter, and Zend), and PHP allows you to work with the web’s most popular CMSs, such as WordPress.
What are the differences between Python v2 and Python v3?
The code syntax is slightly different in v2 and v3. Some keywords are different, and some people feel that Python 3 is slightly slower, although there are many variables on a web server that can affect speed.
If you’re new to Python, it doesn’t matter which version you use, providing you stick with it consistently. But if you want to install an existing Python application, it’s important that your host supports the correct version.
