如何将输入转换为变量，以便我可以在 python 中的方程中添加或使用

Question

if I have a code like this?

num1= input (" number goes here")
num2= input ("number goes here")

how can I make a simple equation work such as.

num3=num2+num1
print ("num3")

and when I do that it outputs

num2num3

I have tried things such as

int=(num1)

Answer 1

You need to convert num1 and num2 into int type because input gives you a str type.

num1 = int(input(" number goes here"))
num2 = int(input("number goes here"))
num3 = num1 + num2
print(num3)
