Write a function shampoo_instructions() with parameter num_cycles. if num_cycles is less than 1, print "too few.". if more than 4, print "too many.". else, print "n : lather and rinse." num_cycles times, where n is the cycle number, followed by "done.". sample output with input: 2 1 : lather and rinse. 2 : lather and rinse. done.

The code written in python and fully commented for this question is given below:

# Create the function shampoo_instructions with the num_cycles parameter input

def shampoo_instructions(num_cycles):

   # Condition if is less than 1, print too few

   if num_cycles < 1:

       print("Too few.")

   # Condition if is greater than 4, print too many

   elif num_cycles > 4:

       print("Too many.")

   # If is in inclusive range [1,4], print the Lather and rinse cycle

   else:

       # Create a for loop to print rinse cycle

       for i in range(num_cycles):

           print("{}: Lather and rinse.".format(i+1))

   # Print an end string for each execution

   print("End-------------------------------------")

# Call the function with all the conditions tested

shampoo_instructions(3)

shampoo_instructions(0)

shampoo_instructions(4)

shampoo_instructions(5)
