# 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}) `
