- zip will take two iterables and will create a tuple with each matching element in each one
list1 = ['a','b','c']
list2 = [1, 2, 3]
zip(list1, list2) # return iterable object
list(zip(list1, list2)) # use list type
dict(zip(list1, list2)) # use dict type
- Return index method
[ i2 for i1, i2 in zip(list1, list2) if i1 =='b' ] # output : 2
