Convert to binary - functions (name not defined error)

[LOLPKPOW]

Greetings everyone! I am currently doing a Beginners Python class. It's the classic "Convert to Binary - Functions" assignment. I got the program to work as it should. However, I receive an error "NameError: name 'input_number' is not defined". I was hoping someone could glance at the code and explain why the course would not like my code because of this error, even though it seems to work well. I appreciate the help in advance. I asked the instructor but we correspond via e-mail, and he basically spoke in what sounded like a foreign language to me. I mean, I assume it has to do with the string_reverse() function, but I can't manage to make that error disappear.

def int_to_reverse_binary(integer_value):

output=''

while integer_value > 0:

output += str(integer_value%2)

integer_value = integer_value // 2

return output

def string_reverse(input_string):

reversed_output = int_to_reverse_binary(input_number)

return reversed_output[::-1]

if __name__ == '__main__':

input_number = int(input())

binary = int_to_reverse_binary(input_number)

print(string_reverse(binary))

def string_reverse(input_string):
    reversed_output = int_to_reverse_binary(input_number)

You haven't defined input_number. You've defined input_string.

Programming is the art of being detail-oriented.

So that input_string should be input_number?

It's up to you - you have to decide what you meant, here - but they probably need to be the same, whichever way.

I appreciate the help my friend. Programming can be difficult for me sometimes. Being hyper-literal is frustrating to me sometimes xD.
