compare to lists python code example
Example 1: compare lists element wise python
[ x&y for (x,y) in zip(list_a, list_b)]
Example 2: compare two list in python
>>> s = ['a','b','c']
>>> f = ['a','b','d','c']
>>> ss= set(s)
>>> fs =set(f)
>>> print ss.intersection(fs)
**set(['a', 'c', 'b'])**
>>> print ss.union(fs)
**set(['a', 'c', 'b', 'd'])**
>>> print ss.union(fs) - ss.intersection(fs)
**set(['d'])**
