Difference of input() in python2/3 [duplicate]

Question

This is to be a simple mathematics program for my child to help with arithmetic.

However, the IF statement does not work in Python3 but does in Python2!

Please may I ask what has changed (as I can't seem to find the answer)?

#import from library import random import sys #display the python version print(sys.version) #computer selects two random numbers between 1 and 10 x = random.randint(1,10) y = random.randint(1,10) #print x and y values print("For x =", x, "and y =", y) #calculate the correct answer to the sum of the two numbers and store it in the variable named "correct" correct = x + y #ask the user what is the sum of the two random numbers and provide a response answer = input("What is the sum of x plus y ? ") if answer == correct: print("well done") else: print("Incorrect. The correct answer is", correct)

Look at the linked duplicate, input in python3 returns a string of the written input. input in python2 evaluated this as python code, returning an integer if an integer is written. — YSelf

Data type of answer is string, After changing it to int it will work fine

import random import sys #display the python version print(sys.version) #computer selects two random numbers between 1 and 10 x = random.randint(1,10) y = random.randint(1,10) #print x and y values print("For x =", x, "and y =", y) #calculate the correct answer to the sum of the two numbers and store it in the variable named "correct" correct = x + y #ask the user what is the sum of the two random numbers and provide a response answer = input("What is the sum of x plus y ? ") if(int(answer)==correct): print("well done") else: print("Incorrect. The correct answer is", correct)
