Count frequency of each element Dry Run in PYTHON

Count frequency of each element is an interactive PYTHON dry run visualizer from the Lists programs section. Study the source code, then use the execution controls to follow each step, variable update, highlighted line, and console output.

This page provides a browser-based dry run with source-code highlighting, auto-scroll, voice narration controls, and execution output for learning the program step by step.

Count frequency of each element Program Code

# Count frequency of each element
elements = [1, 2, 2, 3, 1, 4, 2, 5, 1, 4, 2, 3]
print("List:", elements)

# Method 1: Using dictionary
freq = {}
for item in elements:
    if item in freq:
        freq[item] += 1
    else:
        freq[item] = 1

print("Frequency count:")
for key, value in freq.items():
    print(f"  {key}: {value} times")

# Method 2: Using collections.Counter
from collections import Counter
counter = Counter(elements)
print(f"\nUsing Counter: {dict(counter)}")
