User input not defined

Question

I can't test the code on this app so I did it on another app called qpython. Every time it says that whatever input is put in is not defined? Is it because I'm using a list? Thanks in advance

print("Guess three colors that I am thinking of!")

colors = ["red", "white", "blue"]

while True:
guess = input(">>> ")
if guess in colors:
colors.remove(guess)
print("Very good! Guess again")
if guess not in colors:
print("Guess Again!")
if len(colors) == 0:
print("You guessed all three colors! You win!")
break

# Still working on this code

Answer 1

It works for me.

You can test it on Sololearn. Give all input at once. On three lines (Or more). Like this.

red
white
blue

Then press submit.

Answer 2

Like this it may work the way you want it to:

while True:
guess = input(">>> ")
if guess in colors:
colors.remove(guess)
if len(colors) == 0:
print("You guessed all three colors! You win!")
break
else:
print("Very good! Guess again")
else:
print("Guess Again!")

Answer 3

Which version of qpython are you using? It might be python 2. Your code works on python 3.

Answer 4

Paul Jacobs oh thank you! I forgot to put all 3 in the input rather than 1 so it does work on there. Now my only question is how can I make it say guess again only for when you guess the first two? I've tried using

if guess in colors and if len(colors) > 1:

so that it would print "very good guess again, but after you guess the third color, it still says to guess again
