PYTHON!!! A bit shift is a procedure whereby the bits in a bit string are moved to the left or to the right. For example, we can shift the bits in the string 1011 two places to the left to produce the string 1110. Note that the leftmost two bits are wrapped around to the right side of the string in this operation. Define two scripts, shiftLeft.py and shiftRight.py, that expect a bit string as an input. The script shiftLeft shifts the bits in its input one place to the left, wrapping the leftmost bit to the rightmost position. The script shiftRight performs the inverse operation.

PYTHON!!!

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

For example, we can shift the bits in the string 1011 two places to the left to produce the string 1110. Note that the leftmost two bits are wrapped around to the right side of the string in this operation.

Define two scripts, shiftLeft.py and shiftRight.py, that expect a bit string as an input.

  • The script shiftLeft shifts the bits in its input one place to the left, wrapping the leftmost bit to the rightmost position.
  • The script shiftRight performs the inverse operation.
  • Each script prints the resulting string.

An example of shiftLeft.py input and output is shown below:

Enter a string of bits: Hello world!

ello world!H

 

An example of shiftRight.py input and output is shown below:

Enter a string of bits: Hello world!

!Hello world
 
 

The program produces correct output for given input.

 

Test Case:

SL Hello world!

 

 Input:

Hello world!

 

Results:

ello world!H
 
 
 
Test Case:

SL Say 'what' again.

 
 
Input:
Say 'what' again.
 
 
Results:
ay 'what' again.S
 
 
Test Case:

SL What a lovely day

 

Input:

What a lovely day

 

 

Output:

hat a lovely dayW
 
 
 
 
Test case:

SR Hello world!

 
 
Input:
Hello world!
 
 
 
Results:
!Hello world
 
 
 
 
Test case:

SR Say 'what' again.

 
 
Input:
Say 'what' again.
 
 
 
Results:
.Say 'what' again
 
 
 
 
Test case:

SR What a lovely day

 
 
Input:
What a lovely day
 
 
 
Results:
