Prompt the user to input either a "yes" or a "no"[edit]

Swift[edit]

// Prompt the user for 'yes' or 'no'
var line : String?
repeat {
     print("Please enter 'yes' or 'no' ->", terminator:"")
     line = readLine()
} while (line == nil || (line! != "yes" && line! != "no")) 

// By the time we get here, line! is either "yes" or "no"

Python[edit]

text = input("Please enter 'yes' or 'no' ->")
while text != "yes" and text != "no":
    text = input("Please enter 'yes' or 'no' ->")
