The error was caused by a typo. Please flag this question as off-topic.
I am having a little issue with the following lines.
from __future__ import print_function
print()
If I open up my Windows CLI and run it, it runs as expected.
When I stick it in a program and execute it, instead of simply printing a newline, it prints ().
Has anybody run into this before?
Additional Details:
If I run a program with just those two lines, it runs as expected.
But for some reason, in my program print() prints (). If I replace that line with print(1), it prints 1 as it should.
Running on Windows 8 64-bit. Python 2.7.11 (v2.7.11:6d1b6a68f775)
Minimal, complete, and verifiable example:
class A:
def f(self):
print()
if __name__ == '__main__':
a = A()
a.f()
Final Update:
Oh my!!!! I am an idiot.
I have a driver program that has the future import, but the class (which is another file) does not! I do have statements like print('abc', file=sys.stderr), but they were not being executed, so the program ran no problem.
My example above actually runs fine. The example I was running didn't have the import. The file I was editing (otherwise an exact copy of the example) did.
Woops!!!!
