Question

A bit shift is a procedure whereby the bits in a bit string are moved to the left or to the right.

Answer 1

Answer:

Following are the code to this question:

Defining method shiftLeft:

def shiftLeft(bit_string): #defining method shiftLeft, that accepts parameter bit_string

   bit_string= bit_string[1:]+bit_string[0]#use bit_string to provide slicing

   return bit_string#return bit_string value

bit_string =input("Enter value: ")#defining bit_string variable for user input

print (shiftLeft(bit_string))#use print method to call shiftLeft method

Defining method shiftRight:

def shiftRight(bit_string):#defining method shiftRight, which accepts bit_string variable

bit_string=bit_string[len(bit_string)-1]+bit_string[0:len(bit_string)-1]#using bit_string variable for slicing

   return bit_string#return bit_string calculated value

bit_string= input("Enter value: ")#defining bit_string variable for user input

print(shiftRight(bit_string))#use print method to call shiftLeft method

Output:

Explanation:

method description:

• In the above-given python code two methods "shiftLeft and shiftRight" are declared, in which both the method accepts a string variable "bit_string".
• Inside methods, we use the slicing, in which it provides to use all the sequence values and calculated the value in this variable and return its value.  
• At the last step, the bit_string variable is used to input value from the user end and call the method to print its value.
