I tried a simple operation in the code playground and the result displayed No Result

Answer 1

you should show us your code here with a link to sololearn.

Answer 2

ok , that's great! So i suppose you did your trials in a .py file and execute it. You can also use the console of a regular IDE ( not in sololearn) to test some expressions:

>>> 2+2
4
>>> (12 + 7) * (14 - 8)
114
>>> 'hello'.upper()
'HELLO'

Answer 3

before I just typed in 2+2
instead of print(2+2)..... it works now as I put print
