Array updating problem for using map(int,input().split()) in python

Question

for taking list input in the array I used

map(int,input().split())

but for using this input method I can't modify the array if I Iterated like a[I] then it shows

TypeError: 'map' object is not subscriptable

Can you please tell me how can I resolve this problem? I am a competitive programmer but I am new to python I must have take input array by using map(int,input().split())

`thing = [int(item) for item in input().split()]`, `thing[I]` — wwii, Dec 10 '21 at 14:50
@wwii. I think it's a challenge so the function is `map(int,input().split())` and can't be a comprehension. — Corralien, Dec 10 '21 at 14:51

Use list(map(int,input().split())) instead of map(int,input().split()) to convert your input to list, because map function returns an generator which can not be indexed.

Thank you so much.. but can you tell me what's wrong in without list? – Ahsan Amin Dec 10 '21 at 14:46

`map` function returns an generator. Generator can not be indexed like `x[i]`. Read more about generators in python [here](https://wiki.python.org/moin/Generators). – Ratery Dec 10 '21 at 14:50

If you can't use another function like list, use:

# Input: 1, 2, 3, 4, 5
l = [*map(int, input().split())]
print(l)

# Output:
1 2 3 4 5
