如何修复 TypeError: +: 'int' 和 'str' 不支持的操作数类型

Question

I'm coding a calculator and when I ran the program this Error message appeared:

Traceback (most recent call last):
  File "/Users/sergioley-languren/Documents/itt/independent_projects/Mathematical_Calculator.py", line 66, in <module>
    print(x + "+" + y + "=" + mathResult + ".") ; sleep(float(speed))
TypeError: unsupported operand type(s) for +: 'int' and 'str'

This here is the code where the error appears:

print("type in your addition problem with your x variable first. (x variable = your first number) CAUTION: This calculator only supports 2 numbers at the moment.") ; sleep(float(speed))
        x = int(input())
        print("Type in your y variable.") ; sleep(float(speed))
        y = int(input())
        mathResult = x + y
        print(x + "+" + y + "=" + mathResult + ".") ; sleep(float(speed))

Answer 1

In python3: print(x, "+", y, "=", mathResult, ".")

Answer 2

Just try putting commas instead of + :

print x , "+" , y , "=" , mathResult , "."

Answer 3

If you are on python 3.6.

print(f"{x} + {y} = {mathResult}.")
