Question

I have the following list in Python:

[('1','2','3'),('5','6','7')]

I need to convert the tuples inside the list into integer([(1,2,3),(5,6,7)]) in a functional way.

I can do them for a list using this simple code: map(lambda x:int(x),['1','2','3'])

But how shall i apply the same concept for list of tuples ?

(I know the imperative way of doing this.)

Answer 1

tl = [('1','2','3'),('5','6','7')]
[tuple(int(x) for x in t) for t in tl]
# [(1, 2, 3), (5, 6, 7)]

If you really want the map syntax,

map(lambda t:tuple(map(int, t)), tl)
# [(1, 2, 3), (5, 6, 7)]
