getting a list after a map() function call

Question

I have the following python program

ml = [x for x in range(1,4)]
f = lambda x : x*2

print(f(ml))

nl = map(f,ml)
print(nl)

The output is given below.

[1, 2, 3, 1, 2, 3]
<map object at 0x1005fada0>

map() is returning a map object is it possible to turn that into a list?

Unlike 2.7, map returns an iterator in Python 3. – Ozgur Vatansever Dec 03 '15 at 06:27 — Ozgur Vatansever, Dec 03 '15 at 06:27

Probably you are using python 3.x. Cast the map object to a list.

n1 = list(map(f,m1))

Yes. Send it to list().

n1 = list(n1)
