Python2 Online Compiler / Interpreter
Write, run, and test legacy Python 2 code online directly from your browser with our free Online Python 2 Compiler / Interpreter. It is useful for maintaining older scripts, checking Python 2 syntax, and studying legacy codebases without installing Python 2.7 or managing multiple local Python environments.
Note: Python 2 has reached end-of-life and is no longer recommended for new production projects. Use this compiler primarily for learning, compatibility testing, migration work, and maintaining existing Python 2 applications.
How to Use This Python 2 Compiler
- Write or paste your Python 2 code
Enter your script in the Code Editor. You can test variables, loops, functions, lists, dictionaries, classes, and other Python 2 syntax supported by the execution environment. - Click the Run button
Select Run to execute your Python 2 program. If the script contains a syntax or runtime error, review the returned message, correct the relevant line, and run the code again. - Check the Output screen
Your program result appears in the Output panel. Use the available controls to copy, download, or delete the output before testing another legacy Python script.

1. What is the difference between printing in Python 2 and Python 3?
In Python 2, print is normally a statement:
In Python 3, print() is a function:
Python 2 can also use function-style printing when print_function is imported from __future__:
This difference is important when migrating older Python 2 programs to Python 3.
2. How do I take user input in Python 2 using raw_input()?
Python 2 commonly uses raw_input() to read text entered by a user:
raw_input() returns the entered value as a string. Interactive input depends on how standard input is implemented by the online execution environment.
Python 2 also has input(), but it evaluates the entered text as a Python expression, so raw_input() is generally the safer choice for normal text input.
3. Do I need to install Python 2.7 on my computer to use this compiler?
No. You can use this Online Python 2 Compiler / Interpreter directly from your browser without installing Python 2.7 locally for supported scripts.
A local Python 2 environment may still be required when maintaining older applications that depend on specific packages, system libraries, databases, filesystem access, or other legacy dependencies.
4. Can I use Python 2 standard library modules in this compiler?
Standard-library modules available in the configured Python 2 runtime can generally be imported and used.
For example:
Support for third-party packages or older modules with external dependencies may vary. If you are maintaining a legacy project, also check whether the package has a Python 3-compatible replacement before continuing long-term development.
