Question
in python pls

Transcribed Image Text:Complete the even_parity() function that takes a single string parameter - bit_string. This string will consist of a sequence of 0's and/or 1's and have a length of at least 1. The function counts the number of 1's in the parameter string. If the
number of 1's is even, the function returns a new string consisting of the parameter string with a "0" concatenated to the end. If the number of 1's is odd, the function returns a new string consisting of the parameter string with a "1" concatenated to
the end. Some example of the function being called are shown below.
For example:
Test
bit_string = "1100001"
print(f"{bit_string} --Even Parity--> {even_parity(bit_string)}")
bit_string = "1100000"
print(f"{bit_string} --Even Parity--> {even_parity (bit_string)}")
Result
1100001 --Even Parity--> 11000011
1100000 --Even Parity--> 11000000
