Does a program press enter between inputs?

Question

Seeing the sololearn code playground and knowing that to differenciate multiple inputs you need to press enter. Does this mean that it is required for all programs to do this to differenciate inputs?

Answer 1

Yes.
If you have many inputs. put each in its own line.

Unless you use code like this: (Python)

x, y, z = [i for i in input().split()] # this way you can put 3 inputs in the same line
# separated by space
