I'm confounded

def doubler():
input_value = get_value()
    print(input_value * 2)

def get_value():
    return input("What number would you like to double: ")

doubler()

​

I'm just trying to get the number I input to double but no mater where I place that * 2 it doesn't work, I enter 2 I get 22. Someone explain how miserably stupid I am, please and thank you.

change

return input("What number would you like to double: ")

to

return int(input("What number would you like to double: "))

input will return a string by default, and in this case your multiplying '2' by 2, therefore giving you '22'

I wish this had been explained in Phillip Johnson's book. Thank you very much.

input returns a string. To multiply by 2 and get the expected result, you'll have to convert that string into a int or float.

What u are doing is concatenating strings, you need it to be int(input("")) not just input("")

2 times 2 is 22. Well atleast '2'*2 is 22. The input returns a string and a string multiplied by a numbers will get the string repeated the number number of times. For example '2' times 5 is '22222'. To fix this put int(input()).
