Syntax Error Whenever I Try To Use Sys.stderr

I've got a problem using the standard error, whenever I try to use it my computer gives me a syntax error which i can't explain. So this is my code: import sys def main(argv): if

Solution 1:

You think you're using Python 3.x, but it's actually Python 2.x. On most systems python executable means Python 2.x.

print is not a function in Python 2.x, and can't be used like that, causing a syntax error.

You should look for some way to run Python 3.x instead.

For this particular case, you could also use from __future__ import print_function, which would make the code compatible with both versions.

Solution 2:

There is a way to fix it

Just remove the "file=" from print method

e.g:

print("Usage: python walk.py n l", sys.stderr)
