Question

Write a Python program string_functions.py that defines several functions. Each function re-implements Python's built-in string methods

Answer 1

Answer:

def length( mystring):

   count = 0

   for i in mystring:

       count += 1

   return count

def reversed( mystring):

   strlist = []

   for i in range(length(mystring)):

       strlist.append(mystring[(length(mystring) - 1) - i])

       txt = "".join(strlist)

   return txt

string = 'Yolanda'

print(reversed(string))

Explanation:

The python module defines two functions 'reversed' and 'length'. The length function counts the number of characters in a string variable while the reversed function reverses the string variable value.
