How to check an array exist in a file using Python

[ichabod801]

A few things: One, list is a bad name for a list. It's the Python function for creating a list, and by using the name elsewhere you are cutting off code that might mess up something else. Two, Array == line[:4] is already a bool, you don't need to convert it to one. Three, bool is a subclass of int, to convert it to 1 or 0 you just need int(found).

Typing all that up made me figure out the problem: you want the second for loop to be over output_list, not list.
