Why can't I `print __doc__` in Python 3?
Question:
I have this code:
#!/usr/local/bin/python
"""
USAGE:
apache_logs.py
"""
import sys
import os
if __name__ == "__main__":
if not len(sys.argv) > 1:
print __doc__
sys.exit(1)
infile_name = sys.argv[1]
I get an error that says
Tue Jul 21{stevenhirsch@steven-hirschs-macbook-pro-2}/projects/python:-->./apache_logs.py
File "./apache_logs.py", line 17
print __doc__
^
SyntaxError: invalid syntax
Why? The documentation I’ve read all seems to suggest it should work.
Answers:
What version of Python do you have? In Python 3, print was changed to work like a function rather than a statement, i.e. print('Hello World') instead of print 'Hello World'
I can recommend you to keep using Python 2.6 unless you’re doing some brand new production development. Python 3 is still pretty new.
