How do I compare 2D lists for equality in Python?

Question

Given two lists:

a = [[1,2],[3,4]]
b = [[1,2],[3,4]]

How would I write compare such that:

compare(a,b) => t         


        

Answer 1

Simple:

def compare(a, b): return a == b

Another way is using lambda to create an anonymous function:

compare = lambda a, b: a == b
