what is type error? how to clear that?

Question

ex:Traceback (most recent call last): File "./Playground/file0.py", line 1, in <module> print(-7 + 2) + (-4) TypeError: unsupported operand type(s) for +: 'NoneType' and 'int'

Answer 1

You make a subtraction of -4 on the print instead of inside the print
