Why doesn’t this code work?

Question

num1 = input()
num2 = input()
print(int(num1))
print(int(num2))
print(int(num1)+=int(num2))

It is saying there is a syntax error... Can anyone tell me why?

Answer 1

num1 = int(input())
num2 = int(input())
print(num1)
print(num2)
print((num1)+num2)

just declare int once per var input and yes get rid of the equal sign

Answer 2

because you put an equal sign after a plus sign.
delete the equal (=) sign after the plus (+) sign and your code will work.

Answer 3

depending on what you're trying to achieve, you could also do:

num1 += num2
print(num1)

+= is kind of shortcut for:

num1 = num1 + num2

this will works without error as soon as num1 and num2 values are of same type...

however, doing:

print(num1 += num2)

will not display expected result but None instead, as in Python assignement doesn't return anything (None) ^^

Answer 4

obviously if you want to add two numbers but you get it through input (string), you must convert them before to numbers:

num1 = int(num1)
num2 = int(num2)

else you will concatenate the two string rather than add the two numbers ;)
