Question

I was about to test the ftpmirror builtin script (python322, winXP 32bits) from the cmd windows default shell and get this :

File "C:\Program Files\python322\Tools\Scripts\ftpmirror.py", line 161
print('Skip pattern', repr(pat), end=' ')
                                    ^
SyntaxError: invalid syntax

I tested the print() line directly in the python shell, trough cmd, and with idle (and in blender also) : this work obsiously.

I reproduce the error with a coucou.py file like this :

#! /usr/bin/env python3
pat = 'toto'
print("Skip pattern", repr(pat), end=" ")

when directly called from a cmd prompt :

C:\Program Files\python322\Tools\Scripts>coucou.py

same error than with ftpmirror
but :

C:\Program Files\python322\Tools\Scripts>python coucou.py

is ok

and my environment is ok I can execute py scripts directly from the windows ui by double-clicking a .py file, and I got working scripts working fine when called from .bat

I don’t get it, it looks specific to the print() end argument, what did I not read yet about the way to execute python3 from the windows cmd shell ?

thanks,

Jerome

Try checking if you are running the same python interpreter when you double click or you run python from the command-line.

Save this in a .py file with this content and try running it with both methods:

import sys
print sys.version_info

I bet you are using different interpreters in each case.
