While loop not working in Python

Question

The while loop is not working properly. The again variable will dictate whether or not the while loop will be executed again. If again = 1, then the while loop will be executed and the program will run again. If again =0, then it will not.

For some reason, again=1 always, so no matter what, while loop is always being executed. Does anyone notice an error in the code?

 score = 0
 loops = 0
 again = 1
 while (again != 0):
    import random
    real = random.randint(1,9)
    fake1 = random.randint(1,9)
    fake2 = random.randint(1,9)
    comb = random.randint(1,9)
    rep = 0
    guess = 0

    if (comb == 1 or comb == 2 or comb == 3):
        print(real, fake1, fake2)
        loops += 1
        guess = int(input("Choose between these numbers"))
        if (guess == real):
            score += 1
            print ("Congrats!")
        else:
            print ("Wrong, better luck next time!")
    if (comb == 4 or comb == 5 or comb == 6):
        print (fake1, fake2, real)
        loops += 1
        guess = int(input("Choose between these numbers"))
        if (guess == real):
            score += 1
            print ("Congrats!")
        else:
            print ("Wrong, better luck next time!")

    if (comb == 7 or comb == 8 or comb == 9):
        print (fake2, real, fake1)
        loops += 1
        guess = int(input("Choose between these numbers"))
        if (guess == real):
            score += 1
            print ("Congrats!")
        else:
            print ("Wrong, better luck next time!")
    again == int(input("Do you wanna go again?"))
    print(again)

again == isn't assignment, it's checking for equality.

You use a comparison operator while assigning a value into variable called again :

again == int(input("Do you wanna go again?"))

You must delete one of the equals signs:

again = int(input("Do you wanna go again?"))

I feel dumb, such an easy fix. Thanks!

again == int(input("Do you wanna go again?"))

This is not going to do what you think, because == means it is checking if this statement is true. You want to have a single =.

For this line:

again == int(input("Do you wanna go again?"))

The ‘==‘ is what you use for returning a Boolean of either True or false when comparing two values. For example:

print(2 > 1)
# output: True

The code should be corrected to:

again = int(input("Do you wanna go again?"))
