Sum of elements stored inside a tuple

Sum of elements stored inside a tuple

You can use

map

and

sum

function like
this

>>> li = [(1, 2), (1, 3), (2, 3)]>>> map(sum, li)[3, 4, 5]

Alternatively you can use list
comprehension, like this

>>> [sum(tup) for tup in li][3, 4, 5]

Note: I personally prefer the list comprehension version, because

map

function in
Python 3.x will return an iterable

map

object, which needs to be explicitly
converted to a list, like this

list(map(sum, li))

.

>>> li = [(1, 2), (1, 3), (2, 3)]>>> map(sum, li)<map object at 0x7f3dc25bb0f0>>>> type(map(sum, li))<class 'map'>>>> list(map(sum, li))[3, 4, 5]

But list comprehension will give a list in both Python 2.x and Python 3.x.
