How to add a number to a variable in python?

Question

num1 = 29
num1 + 1
print(num1)

Output is 29 , but i want num1 to be 30

You didn't assign the result of `num1 + 1` to a name. Try `num1 = num1 + 1` instead. — metatoaster, May 20 '21 at 05:17

You assigned num1 to 29. So, when you print num1, 29 would be the output. Try assigning the answer as "sum".

num1=29
sum = num1 + 1
print(sum)

This should show the correct answer.
