This is for Python code.

17.1 HW8 Part A: Two's Complement
One popular method to store negative numbers in Binary is Two's Complement.
To convert a positive number to Two's Complement requires two steps.
. Fit all bits (1 to O and 0 to 1)
Add one to the result
As an 8-Bit Number
8 00001000
Step 1: Flip All bits
11110111
Step 2: Add 1
Remember the number of bits does not change. If a 1 is carried to the end of the number it is dropped
Write a function twoscomp(num) that takes a string of Os and 1s. The function will return a string with the Two's Complement version of
the binary number.
Create an interface that asks the users for a binary number and prints the Two's Complement version. Remember to wrap your interface
with if name"main": so ZyBooks can test your function
Welcome to Two's Complement Creator
Enter a Binary Value:
In Two's Complement:
