def recursive_func ():

x = input ("Are we there yet?")

if x. casefold () = = 'Yes'. casefold ():

return

else:

recursive_func ()

recursive_func ()

Explanation:

We define the required function as recursive_func ().

The first line takes user input. The user input is stored in variable x.

The next line compares the user input to a string yes. The function executes the else block if the condition isn't met, that is a recursive call is executed.

IF condition returns the function. The string in variable X is compared to a string 'Yes'. the casefold () is a string function that ignores the upper/lower cases when comparing two strings. (This is important because a string 'yes' is not the same yes a string 'Yes' or 'YES'. Two equal strings means their cases and length should match).
