Python: Frequency of the tuples in a given list

Last update on December 21 2024 07:25:18 (UTC/GMT +8 hours)

Write a Python program to get the frequency of the tuples in a given list.

Sample Solution:

Python Code:

# Import the Counter class from the collections module
from collections import Counter

# Create a list of tuples 'nums' with inner lists of pairs
nums = [(['1', '4'], ['4', '1'], ['3', '4'], ['2', '7'], ['6', '8'], ['5', '8'], ['6', '8'], ['5', '7'], ['2', '7'])]

# Print a message to indicate the display of the original list of tuples
print("Original list of tuples:")

# Print the content of 'nums'
print(nums)

# Use Counter to count the frequency of tuples after sorting them
result = Counter(tuple(sorted(i)) for i in nums[0])

# Print a message to indicate the display of tuples and their frequency
print("\nTuples", "    ", "frequency")

# Loop through the results and print each tuple and its frequency
for key, val in result.items():
    print(key, " ", val) 

Sample Output:

Original list of tuples:
[(['1', '4'], ['4', '1'], ['3', '4'], ['2', '7'], ['6', '8'], ['5', '8'], ['6', '8'], ['5', '7'], ['2', '7'])]

Tuples      frequency
('1', '4')   2
('3', '4')   1
('2', '7')   2
('6', '8')   2
('5', '8')   1
('5', '7')   1

Previous: Write a Python program to insert an element at the beginning of a given OrderedDictionary.
Next: Write a Python program to calculate the maximum aggregate from the list of tuples (pairs).
