Python coding, please do without importing modules :)

Write a function, encode, with one parameter, letter, a string. encode will add a parity bit to the binary (ASCII) representation of letter. The parity bit should be the most significant (leftmost) character. The new binary representation will be returned. For example,

>>> encode('c') # binary representation of 'c' is 1100011

'0 1100011' # with parity bit leftmost 0

>>> encode('d') # binary representation of 'd' is 1100100

'1 1100100' # with parity bit leftmost 1

Function encode will call another function,parity, to determine the parity bit (0 or 1) for a binary sequence (for 1- bit even parity). F unction parity will have one parameter, bitrep, a string which is a sequence of 0s and 1s, and will return a 1-character string, the parity bit. For example,

>>> parity('1100011') # binary representation of c

'0' # parity bit is 0

>>> parity('1100100') # binary representation of d

'1' # parity bit is 1

Next write function decode, with one parameter, pletter, a string representing the binary sequence, plus parity bit, for a character. Decode should call function parity, to check for even parity in pletter. If no error is detected, decode should convert pletterback to a character, and return the character. If an error is detected, decode should return'*'.

Finally, write a main function that encodes and decodes the characters is a word. For example,

word = 'cat'

for letter in word:

print(decode(encode(letter)), end='')

print()

The last line in your .py file should be a call to function main:

if __name__ == '__main__':

main()

As much explination as you go through your code what be great!

this is what i have so far...

def encode(letter):

letter_to_asc11 = ord(letter) add_binary = bin(letter_to_asc11) #print(add_binary) add_parity = bitrep parity(bitrep)
