How do I get the user to input a number in Python 3?

Question

I'm trying to make a quiz using Python 3. The quiz randomly generates two separate numbers and operator. But when I try to get the user to input their answer, this shows up in the shell:

<class 'int'>

I'm not sure what I need to do. Even if I type in the correct answer, it always returns as incorrect.

import random

import operator

operation=[

    (operator.add, "+"),
    (operator.mul, "*"),
    (operator.sub, "-")
    ]
num_of_q=10
score=0

name=input("What is your name? ")
class_name=input("Which class are you in? ")
print(name,", welcome to this maths test!")


for _ in range(num_of_q):

    num1=random.randint(0,10)

    num2=random.randint(1,10)

    op,symbol=random.choice(operation)

    print("What is",num1,symbol,num2,"?")

    if input(int)==(num1,op,num2):

          print("Correct")
          score += 1
    else:
          print("Incorrect")

if num_of_q==10:

        print(name,"you got",score,"/",num_of_q)

Do you want if int(input('Enter the number: '))==(num1,op,num2):？ — Remi Guan

@KevinGuan that should be an answer, that is probably what OP is looking for — Preet Kukreti

I tried this and it works, but the answers still come up with incorrect. — CyberSkull311

This line is incorrect:

if input(int)==(num1,op,num2):

You must convert the input to int and apply op to num1 and num2:

if int(input()) == op(num1, num2):

Furthermore, input(x) uses x as the message to print, where x is implicitly converted to a str. int by itself is the name of a type. A type's str is usually its repr and for int, that returns the string "<class 'int'>". This indicates why you were getting that message.

@CyberSkull311 Please remember accept the correct answer.

You almost had it working. The reason for the error was you were telling the input command to display an int as a prompt, rather than converting the returned value into an int.

Secondly your method for calculating the answer needed fixing as follows:

import random
import operator

operation=[
    (operator.add, "+"),
    (operator.mul, "*"),
    (operator.sub, "-")
    ]

num_of_q = 10
score = 0

name=input("What is your name? ")
class_name=input("Which class are you in? ")
print(name,", welcome to this maths test!")

for _ in range(num_of_q):
    num1=random.randint(0,10)
    num2=random.randint(1,10)
    op, symbol=random.choice(operation)
    print("What is",num1,symbol,num2,"?")

    if int(input()) == op(num1, num2):
          print("Correct")
          score += 1
    else:
          print("Incorrect")

print(name,"you got",score,"/",num_of_q)
