Uses of Python's “from” keyword?

Question

Are there any other uses for Python\'s \"from\" keyword aside from import statements?

Answer 1

Since there are a lot of updates to python from the time of posting the question, here is a new use case of from keyword in python3 will show you the use with an example

def flatten(l):
    for element in l:
        if type(element) == type(list()):
            yield from flatten(element)
        else:
            yield element

def flatten2(l):
    for element in l:
        if type(element) == type(list()):
            yield flatten2(element)
        else:
            yield element


unflatted_list = [1,2,3,4,[5,6,[7,8],9],10]
flatted_list = list(flatten(unflatted_list))
flatted_list2 = list(flatten2(unflatted_list))
print(flatted_list) # [1,2,3,4,5,6,7,8,9,10]
print(flatted_list2) # [1, 2, 3, 4, , 10]
