Python program to unique keys count for Value in Tuple List
When it is required to get the count of unique keys for values in a list of tuple, it can be iterated over and the respective counts can be determined.
Below is a demonstration of the same −
Example
import collections
my_result = collections.defaultdict(int)
my_list = [[('Hello', 'Hey')], [('Jane', 'Will')], [('William', 'John')], [('Hello', 'Hey')], [('z', 'q')]]
print("The list of list is :")
print(my_list)
for elem in my_list:
my_result[elem[0]] += 1
print("The result is : ")
print(my_result)Output
The list of list is :
[[('Hello', 'Hey')], [('Jane', 'Will')], [('William', 'John')], [('Hello', 'Hey')], [('z', 'q')]]
The result is :
defaultdict(<class 'int'>, {('Hello', 'Hey'): 2, ('Jane', 'Will'): 1, ('William', 'John'): 1, ('z', 'q'): 1})Explanation
The required packages are imported.
A list of list of tuples is defined, that contains string and characters.
The list is displayed on the console.
The list is iterated over, and the first element is incremented by 1.
This result is displayed on the console.
