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 Occurrences of a Given Character Program Code

# Python program to count occurrences of a given character
text = "success"
search_char = 's'

# Method 1: Using count() method
count1 = text.count(search_char)

# Method 2: Using loop
count2 = 0
for char in text:
    if char == search_char:
        count2 = count2 + 1

# Method 3: Using list comprehension
count3 = len([char for char in text if char == search_char])

# Method 4: Using sum() with generator
count4 = sum(1 for char in text if char == search_char)

print("String:", text)
print("Character to count:", search_char)
print("Count (count() method):", count1)
print("Count (loop):", count2)
print("Count (list comp):", count3)
print("Count (sum generator):", count4)
