Caesar Cipher - Problem Solving

Discover two methods to implement Caesar Cipher in Python.


Method 1
def solution(text, shift):
    alphabet = 'abcdefghijklmnopqrstuvwxyz'
    result = ''

    for char in text:
        if char.isalpha():
            index = alphabet.index(char.lower())
            shifted_index = (index + shift) % 26
            shifted_char = alphabet[shifted_index]
            result += shifted_char.upper() if char.isupper() else shifted_char
        else:
            result += char

    return result

Example Usage​

Input/Output Example
result = solution("abc", 3)

print(result)  # Output: "def"
