I installed successfully newest WinPython v3.13 on Windows 10. The path to python.exe is prepended to PATH environment variable. I can launch python.exe from CommandPrompt simply by entering python.exe. So everything is fine so far. Furthermore I let WinPythons Installer associate the *.py file extension to python.exe Now I created a super simple python file "text.py" with the following content: --version which should obviously be passed to python and executed. But when I double click on test.py or enter at the commandprompt test.py I get the following error: Traceback (most recent call last): File "D:\data\test.py", line 1, in --version ^^^^^^^ NameError: name 'version' is not defined Even if I enter: python test.py the same error occurs. Whats wrong? I though a *.py file will be passed to python interpreter and executed just as I would enter python --version but this seems to be not the case. Whats wrong? python --version works — Reply to this email directly, view it on GitHub <#1421>, or unsubscribe <https://github.com/notifications/unsubscribe-auth/AECBUVC6CCCTCNIUHNGXKITZ3JDIRAVCNFSM6AAAAABP3JTH6OVHI2DSMVQWIX3LMV43ASLTON2WKOZSGU4DGOBVGU2DIMY> .
