Quit function in python programming

I have tried to use the 'quit()' function in python and the spyder's compiler keep says me "quit" is not defined

print("Welcome to my computer quiz")

playing = input("Do you want to play? ")

if (playing != "yes" ):
    quit()
    
print("Okay! Let's play :)")

the output keep says me "name 'quit' is not defined", how can i solve that problem?

Solution

Invert the logic and play if the user answers yes. The game will automatically quit when it reaches the end of the file

print("Welcome to my computer quiz")

playing = input("Do you want to play? ")

if (playing == "yes" ):
    print("Okay! Let's play :)")
