Issue with part 01 e 14 - finding matches

[romain-gonzo]

Here is my code for the problem:

def find_matching(L, pattern):
    l = []
    for x,y in enumerate(L):
        if pattern in y:
            l.append(x)
    return l 

def main():
    pass

if __name__ == "__main__":
    main()

I get an error : test.test_find_matching.FindMatching.test_calls
maximum recursion depth exceeded while calling a Python object

The two other are corrects, when i try my code in IDLE everything work, I have trouble seeing where the problem comes from.
