User clarification.

Question

Sololearn app clarification.
Every time I make a code that needs user input I get a pop saying:
"looks like your prog' needs input"
"split multiple inputs into separate lines"
What is this and what should I do?
Because same code works fine on my laptop.
Also, most of my codes work well on my laptop, but I mostly get syntax errors on this sololearn playground for the same lines of codes.
Help someone.

Answer 1

Because SoloLearn code playground can only handle the input once. If you need more than 1 input on your program, the only way is separate the input.
For example, you need to input 2 integers. What we do is: 1 4

Answer 2

It's a nuisance.
e.g. when you run this code
a = int(input())
b = int(input())
c = int(input())
print(a + b + c)
you have to enter your data like this:
3 hit 'enter' 5 hit 'enter' 2 hit 'submit'
outputs 10
