Question

def list_length(shrinking_list): ''' A recursive way to count the number of items in a list. ''' if shrinking_list

Answer 1

Answer:

Written in Python:

def list_length(shrinking_list):

    if not shrinking_list:

         return 0

    else:

         return list_length(shrinking_list[1:]) + len(shrinking_list[0])

Explanation:

This defines the list

def list_length(shrinking_list):

This checks if list is empty, if yes it returns 0

    if not shrinking_list:

         return 0

If list is not empty,

    else:

This calculates the length of the list, recursively

         return list_length(shrinking_list[1:]) + len(shrinking_list[0])

To call the function from the main, use:

print(list_length(listname))
