Convert string input into integer list in just one line of code in python

Question

input comma separated numbers, convert them into integer from string and then into integer list. this is what i came up with. is there any other way?

x = list(map(lambda x : int(x),(input()).split(",")))

print(x)

input : 1,2,3,55,66,714,78

output : [1, 2, 3, 55, 66, 714, 78]

As your code works, I would suggest this may belong on codereview.stackexchange.com. — Chris

However, I would also suggest: list(map(int, input.split(','))) — Chris

As alluded to by @Chris, the lambda is not needed as map maps each element in the list to int. So answer your question, yes - there are many ways. But this is generally the most efficient. — s3dev

there's also list comprehension

[int(n) for n in input().split(",")]

List comprehension would be slightly faster than list(map())

If you don't mind a tuple, you can use eval

eval(input())
1,2,3,55,66,714,78

(1, 2, 3, 55, 66, 714, 78)
