Python Launcher 25.2

Work with programs and data bundles associated with Python development structures. Use multiple versions of the programming environment and specify associations of Python 2 and 3 with particular elements. Visually track script execution line by line.

Python Launcher is an open-source program that allows Python scripts (.py and .pyw files) on Windows to specify the version of Python which should be used, allowing simultaneous use of Python 2 and 3. When executing a script, the launcher looks for a Unix-style #! (shebang) line in the script. It recognizes executable names python (system default python), python2 (default Python 2 release) and python3 (default Python 3 release).
