To scramble the string, we may choose any non-leaf node and swap its two children. Given two strings of equal length (say n+1), S1[0n] and S2[0n]. (yes or no)") while play=="yes": # pick one word randomly from the sequence word = random.choice (WORDS) # create a variable to use later to see if the guess is correct correct = word # create a jumbled version of the word jumble ="" while word: position = Since the string is immutable, we shall store the characters of the string in a character array ( say li ). Otherwise, it returns False. Thus, ocder is a scrambled string of coder.Similarly, if we continue to swap the children of nodes der and er, it produces a scrambled string ocred. According to Google, this is the definition of permutation: a way, especially one of several possible variations, in which a set or number of things can be ordered or arranged. A list comprehension may not always be the best approach, generator expressions or mappings may be better. Python provides two common ways to check if a string contains another string. as in example?
