Addition Python Function

Question

So I have to create a program that asks the user 5 addition questions and they can type the right answer. I am very new at python and functions in general so helpful answers only please. I know how to get random numbers and make it so the question for ex: "What is 4 + 5?" I just do not know how to ask 5 different addition questions within the function. This is what I have.

import random
def add():
    num1=random.randint(1,10)
    num2=random.randint(1,10)
    return num1,num2



def main():
    x,y= add()
    plus=int(input("What is {} + {} ?".format(x,y)))



main()

When asking about errors, it is important to describe exactly what the error was... please edit your question to add this detail — DNA

Not true, there is no error, at least in Python2.7. Please precise which interpreter version are you using. — Łukasz Rogalski

@Nsh: reading the question, there is error, the OP simply doesn't now how to implement the remaining specs. — willeM_ Van Onsem

I went back and now there is no error but I am unsure how to make it continue to ask an addition question even if the answer given by the user is right or wrong. — Sydney Franklin

I don't get an error when I run your code. Here is an answer for you:

Right now your main() is asking for an input back from the user and each time main() is called it will ask for a different number, so if you like you can do something like this:

for _ in range(5):
    main()

But from the sound of it, you want to have the function main() ask all of the questions, namely - something like this:

def main():
    for _ in range(5):
        x,y = add()
        plus = int(input("What is {} + {} ?".format(x,y)))

Simplest is to use a counting loop:

def main():

    for i in range(5):
         x,y = add()
         plus = int(input("What is {} + {} ?".format(x,y)))

what if I want to tell them the right answer if their answer was incorrect??

@SydneyFranklin: that was not in the original question, and you have already accepted a correct answer. Surely you can figure out a simple if statement yourself? If not, then ask another question.

The following program demonstrates how to have a program ask five addition questions:

import random
import sys

def main():
    for count in range(5):
        ask_addition_question()

def ask_addition_question():
    numbers = random.randrange(10), random.randrange(10)
    answer = get_number('What is {} + {}? '.format(*numbers))
    total = sum(numbers)
    if answer == total:
        print('That is correct!')
    else:
        print('Actually, the correct answer is {}.'.format(total))

def get_number(query):
    while True:
        try:
            return int(input(query))
        except KeyboardInterrupt:
            print('Please try again.')
        except EOFError:
            sys.exit()
        except ValueError:
            print('You must enter a number.')

if __name__ == '__main__':
    main()

Just use a for loop to ask the user 5 times

def main():
    for i in range(5):
         x,y = add()
         plus = int(input("What is {} + {} ?".format(x,y)))

To check if the answer is correct just you can do:

 if x + y == plus: print "good"
 else: print "bad"

How would I tell the user of whatever answer they put is right or wrong , and if wrong show the correct answer?

Sydney Franklin Over a year ago

Since it is randomly generated I am confused how to tell the computer to show the right answer if the user inputed the wrong one.

Daniel Over a year ago

Just have x+y compare to plus, if x+y == plus: "correct"
