Question

Python: Suppose you develop a code that replaces a string with a new string that consists of all the even indexed characters of the original followed by all the odd indexed characters. For example, the string 'computers' would be encoded as 'cmuesoptr'. Write a function

encode(word)

that returns the encoded version of the string named word.

Answer 1

def encode(word):

    # string to store characters at even index

    even = ''

   

    # string to store characters at odd index

    odd = ''

    i = 1

   

    # compute string with characters at odd index

    while i - 1 < len(word):

   

        odd += word[i - 1]

       

        i += 2

       

    i = 2

   

    # compute string with characters at even index

    while i - 1 < len(word):

   

        even += word[i - 1]

       

        i += 2

       

    ans = odd + even

   

    return ans

   

print(encode('computers'))
