Python: Frequency of the elements in a given list of lists
Python List: Exercise - 143 with Solution
Write a Python program to get the frequency of elements in a given list of lists.
Sample Solution:
Python Code:
def count_elements_lists(nums):
nums = [item for sublist in nums for item in sublist]
dic_data = {}
for num in nums:
if num in dic_data.keys():
dic_data[num] += 1
else:
key = num
value = 1
dic_data[key] = value
return dic_data
nums = [
[1,2,3,2],
[4,5,6,2],
[7,8,9,5],
]
print("Original list of lists:")
print(nums)
print("\nFrequency of the elements in the said list of lists:")
print(count_elements_lists(nums))
Sample Output:
Original list of lists: [[1, 2, 3, 2], [4, 5, 6, 2], [7, 8, 9, 5]] Frequency of the elements in the said list of lists: {1: 1, 2: 3, 3: 1, 4: 1, 5: 2, 6: 1, 7: 1, 8: 1, 9: 1}
