Python | Counting the occurrence of tuples in a list of tuples

|

Here are some ways to achieve the above objective.

Method # 1: Using Iteration

# Python code for counting uniqueness
# tuples in the list

 

import collections 

Output = collections.defaultdict ( int )

  
# Initialization list

Input = [[( ’ hi’ , ’bye’  )], [( ’Geeks’ , ’ forGeeks’ )],

[( ’a’ , ’ b’ )], [( ’ hi’ , ’bye’ )], [( ’a’ , ’b’ )]]

  
# Using iteration

for elem in Input :

Output [elem [ 0 ]] + = 1

 
# Printout

print (Output)

Exit:

 defaultdict ("class ’int’ & gt ;, {(’ Geeks’, ’forGeeks’): 1, (’ hi’, ’bye’): 2, (’a’,’ b’): 2}) 

Method # 2: Using chain and Counter

# Python code for counting uniqueness
# tuples in the list

 
# Import

from collections import  Counter

from itertools import chain

 
# Initialization list

Input = [[( ’hi’ , ’ bye’ )], [( ’ Geeks’ , ’forGeeks’ )],

[( ’a’ , ’ b’ )], [( ’hi’ , ’ bye’ )], [( ’a’ , ’b’ )]]

 
# Using counter and chaining

Output = Counter (chain ( * Input ))

  
# Printout

print (Output)

Exit:

 Counter ({(’hi’,’ bye’ ): 2, (’a’,’ b’): 2, (’Geeks’,’ forGeeks’): 1})
