Let say Python is not installed on your system, or you are on the metro, bus, or train and want to execute a program from your smart Phone then what would you do?– The answer is simple you would use an Online Python compiler/interpreter which will execute your code on the web-browser.
Although Python itself is not a heavy software that requires high-end computing power, even single board computers like Raspberry Pi can install and run Python with ease. But it’s good to know the alternative to run a Python program. The Python online interpreters/compilers provide the best interface to write and execute Python programs with efficiency, so you could run a Python program anytime anywhere.
How to Run a Python Program Online?
As Python is one of the best programming languages out there, it has the highest number of active developers and tons of libraries to support it in various domains. When you start learning Python you typically install the Python interpreter in your local system to run Python program files with .py extensions. If you do not install the Python interpreter in your system, you would not be able to execute the Python program, and this same thing goes for other High-Level programming languages like Java, C++, etc.
But if you are working on a guest system, or using your colleague, friends, or family member computer or system, then instead of installing Python on their system you would prefer to use an Online Python Interpreter to execute the Python program.
Right Now there are many Platforms present on the internet which Provide online compilers and interpreters for different programming. With that, you do not have to download the compiler and interpreter for the specific programming language and, compile and execute your code online using the web browser.
Best Online Python Compiler/Interpreter 2021
As Python is an Interpreted Programming language, for the rest of this article we will be using the terms compiler and interpreter interchangeably, although both are completely different terminologies, or say opposite of each other. But in the case of online Python code execution, many online platforms interchangeably use the term Compilers and Interpreters, but in reality, the Platform which executes Python code online is known as Online Python Interpreters.
Now let’s get started with the list of our top online Python Interpreters for 2021.
Repl.it provides a very intuitive and beautiful interface for executing Python programs online. It is one of the best online Python compilers with a dark mode code editor interface.
It is free to use an Online Python compiler, and it can execute your Python code in no time. The output of your Python code will be displayed just on the right side of your source code. Apart from Python3 it also supports code interpreter for Python2 and other different programming languages in case if you wish to execute your C++ or Java code.
Preserving the active sessions is one of the best features of Repl.it Online compiler, you can resume your coding where you left it last time. Although you can use Repl.it Online Python complier without even log in or signup, but if you do you will be introduced to many features such as sharing code on GitHub, create a working directory, etc.
The Pythonanywhere is a Hosting platform that allows you to host Python-based web-applications, but it also provides an unconventional shell-like Online Python compiler. The online python compiler provided by Pythonanywhere is called IPython, which is an interactive Python Interpreter shell for executing a python program.
The IPython is generally used for Python with Data Science, if you are familiar with Jupyter Notebook, you will notice that Python anywhere online compiler interface is pretty much similar to it. This is because Pythonanywhere and Jupyter notebook both use IPython.
Many online Python compilers do not support the import of Python high processing libraries like numpy, pandas, scipy, beautifulsoup, etc. but this is not the case with Pyhtonanywhere. With Pythonanywhere online Python interpreter you do not have to worry about installing these libraries all the important Python Data Science libraries are supported by Pythonanywhere IPython, you can simply import and start using them.
Ideone provides a moderate online Python text editor and compiler tool. It has a pretty simple interface, and it supports more than 55 programming languages. You can simply write your Python code on the provided text editor and hit the Run button to execute the code. And the output of the code will be displayed on the new page.
Ideone will also come with the feature of code visibility which allows you to share your code privately or publically. As compared to other online python compilers ideone can be slow and its output formatting is also a little bit old.
Trinkets is a very powerful online python compiler. With Trinkets, you can execute your Python program from anywhere with any device. Unlike other online compilers, Trinkets is specially designed to execute Python code online. It comes with pre-installed Python popular data science and computational libraries like Pandas, numpy, matplotlib, etc. The support of matplotlib is pretty powerful in the Trinkets online Python compiler. Because many online python compilers do not support matplotlib. But Trinkets not only support but also display graphs on the web browser generated by matplotlib.
OnlineGDB is one of my favorite Online Compilers. OnlineGDB supports more than 20 languages including Python3. It has a beautiful text editor interface, which felt like a standalone text editor of an IDE.
It comes with many features such as beautify code, upload source code, download code, etc. With upload source code you can upload a Python file to this online compile and execute it online. You can also toggle between the light and dark mode text editor, and it also allows you to customize the spaces for tabs and the font size.
Sololearn is the best Mobile application to learn and execute code. It also provides online compilers for different programming languages, by far it only supports online compiler for 12 programming languages including Python.
The Online Python Interpreter provided by Sololearn is very interactive, it also provides options for light and dark Editor mode which is pretty cool. The online code editor of sololearn also supports features like private and public visibility to share your Python program in their platform. If you log into the sololearn then you can also share your Python program with its community.
JDoodle is a fully fledge Online compiler, and it supports more than 50 languages. Although it has a minimal look, it comes with many features that many online Python compilers miss. Let’s first start with its execution speed, it can run your Python program online within no time, and the output of the program will be displayed on the same page.
Once you are done with writing and executing the program you can save it to the online projects which can be accessed later, isn’t it cool. It also provides a toggle feature to toggle between Dark and Light code editor mode. And you can also upload your python from your system and execute it online.
The official Python website, www.python.org provides an online Python shell to execute Python code. The Online Python shell offered by Python.org is similar to the Python interpreter you install on your system.
With the Python.org shell interface, you can execute Python code, not programs. It is only good to check the output of some small python code, but if you are looking for an online Python compiler to run a 100 lines Python program then the Python.org shell is not for you.
OneCompiler is an online Compiler tool that supports 40 different programming languages including Python. It has a minimal interface with toggle light and dark editor mode.
With OneCompiler you can write a Python program, execute it online, and even share it on different social platforms. The execution speed of OneCopiler is also very good and it shows the output of the source code on the same page.
CodePad is a very minimalistic online compiler, as compared to other online python compilers it is very slow. It even does not offer many features, apart from code visibility public or private.
Despite being simple and slow, CodePad will execute your simple python program and give you the appropriate output. Do not expect more from this simple online compiler, you can use CodePad for simple 10 to 20 lines of Python programs.
With this, we have reached the end of our Article “Best Online Python Compiler/Interpreter 2021”. We only suggest using an online python compiler if you do not wish to install Python on your system or you are using a mobile device to check the output of a Python program. Among the top 10 Online Python Interpreters or Online Python Compiler, we have mentioned above ideone, onlineGDB and trinkets are my favorites ones.
