How to test a Python script with an input file filled with testcases?

Question

I\'m participating in online judge contests and I want to test my code with a .in file full of testcases to time my algorithm. How can I get my script to take input from this .i

Answer 1

PyUnit "the standard unit testing framework for Python" might be what you are looking for.

Doing a small script that does something like this:

#!/usr/bin/env python
import sys

def main():
    in_file = open('path_to_file')
    for line in in_file:
        sys.stdout.write(line)

if __name__ == "__main__":
    main()

And run as

this_script.py | your_app.py
