Asking for multiple Variables in one input Python

Question

In the example below I am trying to print the three variables I put in. If I try to separate the different inputs with commas, it gives me this error message:

ValueError: invalid literal for int() with base 10: '20,20,20'

If you need to know more, I'm happy to help.

A, B, C = int(input("how do I do this?"))
print(A)
print(B)
print(C)

I really like your answer @sahasrara62, should probably be the actual answer. But I guess it doesn't really matter as the question is closed now. — André C. Andersen, Feb 13 '21 at 21:06

The following should do what you want:

A, B, C = (int(value) for value in input("how do I do this?").split(','))
print(A)
print(B)
print(C)

When you enter in the input "1,2,3", it's converted to [1, 2, 3] (using the split method) then each variable is assigned to an element of the list.

a, b, c = map(int, input("how do I do this?").split(","))
print(a)
print(b)
print(c)

The type of a, b, c is not correct in this answer. The question is asking for ints, not strings. – André C. Andersen Feb 13 '21 at 21:02
@AndréC.Andersen corrected it, thanks for the comment – sdzt9 Feb 13 '21 at 21:15

I really like this answer too. I use map too seldom. – André C. Andersen Feb 14 '21 at 19:14
