# Take string input
s = input("Enter a string: ")

# Count characters
freq = {}
for char in s:
    freq[char] = freq.get(char, 0) + 1

# Display
for char, count in sorted(freq.items()):
    print(f"{char}: {count}")

Output

Enter a string: hello
e: 1
h: 1
l: 2
o: 1

Use dictionary to count frequency.

Key Concepts:

  • Use dictionary to track counts
  • freq.get(char, 0) returns count or 0
  • Increment for each occurrence
