How to convert .pyc to .py on Windows (Step by Step)

How to convert .pyc to .py on Windows: Steps to Compile and Decompile the Script: 1. Compile the Script into a .pyc File: o Open Command Prompt. o Navigate to the folder where example.py is saved: cd path\to\your\file o Run the following command to compile the Python script into bytecode: python -m compileall o This will create a _pycache_ folder containing the .pyc file. 2. Decompile the .pyc File: o Now, you can use the uncompyle6 tool to decompile the .pyc file back to a .py file: o pip install uncompyle6 uncompyle6 -o output_directory __pycache__\example.cpython-XX.pyc When Does Compiling Happen? 1. During Script Execution: o When you run a Python script (python example.py), Python automatically compiles the .py file into bytecode (.pyc file) and stores it in the _pycache_ directory. o If a compiled version of the script already exists and hasn't changed, Python will reuse the .pyc file to speed up execution. 2. When Importing Modules: o Whenever you import a module in Python, if a compiled version of the module doesn't exist, Python will compile it and store the .pyc file in the _pycache_ folder for future imports. o If the .py file has been modified, Python will recompile it into a new .pyc file. Why Does Python Compile to Bytecode? • Efficiency: Compiling into bytecode improves performance. Instead of interpreting the script line by line each time, Python reads the bytecode, which is faster. • Portability: The .pyc bytecode files are platform-independent, meaning they can run on any system with a compatible Python interpreter. #python #pythonforbeginners #pythontutorial
