Code written in a high-level programming language can be run via two ways (and it refers not only to Python). The first one is to compile the program. It means that a compiler translates high-level instructions directly into machine language. The other way is to “interpret” the program. An interpreter starts with translating high-level instructions into an intermediate form and then executes them.
The most common reason for using the interpreter is its speed. Since a developer can add small sections of code and test them quickly, immediate execution is particularly useful during the development process of a program. Interpreters are also widely used in education because they allow students to program interactively.
There are situations when you do not want to install Python on your computer and need tools that will enable you to run Python scripts online. Maybe you are using a borrowed or public PC, want to share your code, or for any other reason. Regardless of the reason, there is an extensive list of websites that allow running code right in your browser.
repl.it
repl.it is aimed for interactive exploration of programming languages. This online environment provides a fully-featured terminal emulator and code editor, powered by interpreter engines for more than 15 languages, including Python 2+ and Python 3+. You can save and share a session, there is even support for Android devices, and partial support for iOS. It is also run on an open-source basis which allows you to contribute through the GitHub repositories.
SourceLair
sourcelair.com is a cloud-based software development environment that allows developers to work everywhere, with the most reliable, efficient, and elegant development environment available. After registering you can receive free access to this website with fully-featured editor and terminal, SSL protection, public URL, Email support, and GitHub integration.
Python.org
https://www.python.org/ is one of the fastest online pYthon terminals. For your assistance, it contains the following functionality of Python code execution as well as copying and pasting of your commands into the terminal console. This online interpreter also has an upgraded IPython tag for integrated shells operating at the runtime that is a mile better than the default shell in Python. Python.org allows you for quick access to operating system commands and interacts with your text editor.
Ideone
ideone.com is an online compiler and debugging tool which allows users to compile source code and execute it online for Python 2.7 or 3.4. What is more, Ideone allows you to compile source code and execute it online in more than 60 programming languages.
Pythontutor
pythontutor.com educational tool that helps to understand what happens as the computer executes each line of a program's source code. The tool has a shared session, step by step execution for Python 2.7 or 3. After writing your code in the compiler, you see how it is visualized, first, and then you can receive the live help from volunteers and Python enthusiasts.
Python Fiddle
pythonfiddle.com is a simple IDE for Python. With Python Fiddle you can:
- Run any Python application on any computer
- Ship samples from other places
- Download and delete
- Autofill in as you type
- Link to Stackoverflow solutions
- Get it installed as a Python terminal or syntax highlighter
#techmums
techmums.co/python.html is a very simple way to output your Python code. #techmums intends to help mothers become more comfortable, relaxed, and enthusiastic about the usage of technology in their professional and parental lives, but it doesn't mean that it can be used only for mums. This online interpreter is available for everyone.
Rextester
rextester.com/runcode can run and save your Python code. It also supports both variants of Python 2.7 and 3.6. With Rextester, your application will be run from Python wrapper, which establishes specific method limits - the process of compiling durates 30 seconds, ca. 5 sec of running CPU time, and limited memory up to (~1.5 GB). Moreover, your development cycle must operate in a newly formed group of processes.
Learn Python
learnpython.org - an interactive Python tutorial with code examples and their execution online. This website is especially useful for beginners. You can get started with the “Hello, World!” tutorial and proceed to the more advanced ones. Each tutorial ends with a Python 2 or 3 command line field, where you can check the knowledge you gained in the tutorial.
