Python doesn't accept my input, what I'm I doing wrong? [duplicate]

Question

I'm creating code for the mastermind game and I think that everything should be perfect, but when I try to write the info needed by the first input (in this case, the colors like "R", it doesn't matter what I do that will jump directly to print ("You have to introduce four colours, no more, no less! ")

Can anyone help me please???

Here's the code:

colours=["R", "G", "B", "Y", "W", "R", "P"]
attempts=0
game=True


codemaker=random.sample(colours,4)
print (codemaker)

while game:
    white_points=0
    black_points=0
    guessed_colour=""
    player_guess=input().upper()
    attempts+=1

    if len(player_guess) != len(codemaker):
        print ("You have to introduce four colours, no more, no less! ")
        continue

What exactly are you inputing into input? Are you only inputting a single letter? — Carcigenicate

I could not reproduce the error. I suspect your input is faulty. — gmds

the result of input is a string. From your code, your input must be a string of 4 letters, e,g, rgby for the len comparison to work — Henry Yik

Do a little lightweight debugging with print and you will see that the code does exactly what you asked it to do: it doesn't print("You have to introduce four colours, no more, no less! ") when the lengths are the same 4:

import random

colours=["R", "G", "B", "Y", "W", "R", "P"]
attempts=0
game=True

codemaker=random.sample(colours,4)
print(len(codemaker), codemaker)

while game:
    white_points=0
    black_points=0
    guessed_colour=""
    player_guess=input().upper()
    attempts+=1
    print(player_guess, len(player_guess))

    if len(player_guess) != len(codemaker):
        print("You have to introduce four colours, no more, no less! ")
        continue

Testing...

4 ['W', 'B', 'R', 'G']
abcde
ABCDE 5
You have to introduce four colours, no more, no less! 
WBRG
WBRG 4
@#$%^U
@#$%^U 6
You have to introduce four colours, no more, no less!
