Enter a number43
>>> g + 2
Traceback (most recent call last):
  File "<pyshell#7>", line 1, in <module>
    g + 2
TypeError: Can't convert 'int' object to str implicitly

The program wont let me use the input variable in mathematical operations, like g + 2

Answer 1

In python 3, input() returns a string type even if you input a number. Thus, you're trying to add an integer with a string

You need to convert it to an integer type by using int() :

g = int(input("Enter a number"))
