Mock Python's built in print function

Question

I\'ve tried

from mock import Mock
import __builtin__

__builtin__.print = Mock()

But that raises a syntax error. I\'ve also tried patching

Answer 1

First, the module is called __builtins__ and you don't need to import it.

Now, in Python 2 print is a keyword so you can't use it as an attribute name directly. You can use setattr/getattr to workaround it:

getattr(__builtins__, "print")

Another option is to use from __future__ import print_function which changes how Python parses the module to Python 3 syntax.
