Question

I’m trying to write a script that will prompt a user for an answer to an addition problem. To do this I need to pass a variable to the string that is displayed during the prompt but I’m having a hard time figuring out how to do this.

I’ve come up with the following code that does not work:

operand = 4
ans = input('What is 4 + {0} ?') .format(operand)

returns:

'What is 4 + {0} ?'

But I want it to be:

'What is 4 + 4 ?'

How can I do this?

Answer 1

ans = input('What is 4 + {0} ?'.format(operand)) 

You need to modify the string argument to input. In your code you are trying to format the input string returned by the input function
