Python count list

Using collections.Counter:

from collections import Counter

my_list = [1, 2, 2, 3, 4, 2, 5, 6, 4]

# Count occurrences of all elements using Counter
element_counts = Counter(my_list)

# Access counts for specific elements
count_of_2 = element_counts[2]
print(f"Count of 2: {count_of_2}")

# Access counts for all unique elements
for element, count in element_counts.items():
    print(f"Count of {element}: {count}")

The Counter class provides a more efficient way to count occurrences of elements in a list or any iterable.
