In my program, a user selects to have a value chosen at random. If they want to choose again at random how do I loop back a few lines to run that code again?

For context, it's a recipe program. If they don't like the recipe randomly chosen, they can pick at random again.

Loop may be what you want. P.S. It would be helpful to study programming by reading the textbook from the beginning to the end.

user_unhappy = True
while user_unhappy:
    #do stuff
    #do stuff
    user_input = input("ask question")
    #do stuff
    ask_user_happy = input("happy with choice?")
    if ask_user_happy.casefold() == "y" or ask_user_happy.casefold() == "ye" or ask_user_happy.casefold() == "yes":
        user_unhappy = False

I think the solution to this would be to nest one loop within the other. The outer infinite loop for selecting the recipe and the inner loop for going through the lines of the recipe. If the user wants to choose a new recipe, you can break out of the inner loop and show the recipes list again.

while True:
    # Show and select recipe.
    for line in recipe_lines:
        # Show recipe.
        # Break if recipe change
    # Break from outer loop if no new recipe is chosen.
