Python exit codes

Question

Where can I find information about meaning of exit codes of \"python\" process on Unix? For instance, if I do \"python thisfiledoesntexist.py\", I get exit code 2

Summar

Answer 1

The Python manual states this regarding its exit codes:

Some systems have a convention for assigning specific meanings to specific exit codes, but these are generally underdeveloped; Unix programs generally use 2 for command line syntax errors and 1 for all other kind of errors.

So, since you specified thisfiledoesntexist.py as a command line argument, you get a return code of 2 (assuming the file does not, in fact, exist. In that case I'd recommend renaming it to thisfiledoesexist.py. ;) )

Other that such parsing errors, the return code is determined by the Python program run. 0 is returned unless you specify another exit code with sys.exit. Python itself does not interfere.
