Question

THIS IS THE CODE I AM TRYING TO RUN

code

# def main():

      #Reading a as an integer

      a = int(input("Enter value for a: "))

      #reading b as an interger

      b = int(input("Enter value for b: "))

      #reading n as an integer

      n = int(input("Enter value for n: "))

      # displaying if a and b are congruent modulo n, this is True if a and b

      #both returns same remainder when divided by n

      if a % n == b % n:

             print(True)

      else:

        print(False)

      #displaying values of a mod n and b mod n

      print("a mod n:", a % n)

      print("b mod n:", b % n)

      #calling main()

      main()

I AM GETTING THE ERROR BELOW: PLEASE HELP:

There is a couple of errors in your code. On the first line, before def keyword, there is a ‘#’ symbol, which means that the line is commented out, that should be removed or else nothing will work. And secondly, at the end of your main() method definition, you attached the call to invoke main() the indentation is not correct, it should be placed with one less indentation level (should be on the same level as the def keyword in main).

Here is the fixed code for this problem. Go through it, and let me know if you have any doubts or if you need anything to change. If you are satisfied with the solution, please rate the answer. Thanks

Note: Please maintain proper code spacing (indentation), just copy the code part and paste it in your compiler/IDE directly, no modifications required.

def main():
    #reading a as an integer
    a = int(input("Enter value for a: "))
    # reading b as an integer
    b = int(input("Enter value for b: "))
    # reading n as an integer
    n = int(input("Enter value for n: "))
    # displaying if a and b are congruent modulo n, this is True if a and b
    #both returns same remainder when divided by n
    if a % n == b % n:
        print(True)
    else:
        print(False)
    #displaying values of a mod n and b mod n
    print("a mod n:", a % n)
    print("b mod n:", b % n)

#calling main()
main()
