Python – Tuple elements inversions

  • Last Updated : 19 Feb, 2020

Sometimes, while programming, we have a problem in which we might need to perform certain bitwise operations among tuple elements. This is an essential utility as we come across bitwise operations many times. Let’s discuss certain ways in which this task can be performed.

Method #1 : Using map() + list() + tuple() + lambda + "~" operator
The above functions can be combined to perform this task. We can employ map() to accumulate the result of Inversion logic specified by the lambda function. The list() and tuple() functions are used to perform interconversions.




# Python3 code to demonstrate working of 
# Tuple elements inversions
# Using map() + list() + tuple() + lambda + "~" operator 
  
# initializing tup 
test_tup = (7, 8, 9, 1, 10, 7
  
# printing original tuple
print("The original tuple is : " + str(test_tup)) 
  
# Tuple elements inversions
# Using map() + list() + tuple() + lambda + "~" operator 
res = tuple(list(map(lambda x: ~x, list(test_tup)))) 
  
# printing result 
print("The Bitwise Inversions of tuple elements are : " + str(res)) 
Output :
The original tuple is : (7, 8, 9, 1, 10, 7)
The Bitwise Inversions of tuple elements are : (-8, -9, -10, -2, -11, -8)

 

Method #2 : Using map() + tuple() + list() + operator.invert
This task can also be performed using this method. In this the task performed by lambda function in above method is performed using ior function for cumulative Inversion operation. The list() and tuple() functions are used to perform interconversions.






# Python 3 code to demonstrate working of 
# Tuple elements inversions
# Using map() + list() + tuple() + operator.invert 
from operator import invert 
  
# initializing tup 
test_tup = (7, 8, 9, 1, 10, 7
  
# printing original tuple
print("The original tuple is : " + str(test_tup)) 
  
# Tuple elements inversions
# Using map() + list() + tuple() + operator.invert 
res = tuple(list(map(invert, list(test_tup)))) 
  
# printing result 
print("The Bitwise Inversions of tuple elements are : " + str(res)) 
Output :
The original tuple is : (7, 8, 9, 1, 10, 7)
The Bitwise Inversions of tuple elements are : (-8, -9, -10, -2, -11, -8)
