Program Code โ€“ Unlocking Python: A Collection of Codes for Aspiring Developers

import random

# Function to generate a random password
def generate_password(length):
    # Define the characters that our password can contain
    chars = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!@#$%^&*()?'
    password = ''
    for i in range(length):
        password += random.choice(chars)
    return password

# Function to encode a given string using a simple caesar cipher
def caesar_cipher_encode(text, shift):
    result = ''
    # Traverse the text
    for i in range(len(text)):
        char = text[i]
        # Encrypt uppercase characters
        if char.isupper():
            result += chr((ord(char) + shift-65) % 26 + 65)
        # Encrypt lowercase characters
            result += chr((ord(char) + shift-97) % 26 + 97)
    return result

# Function to decode a string encoded with a caesar cipher
def caesar_cipher_decode(text, shift):
    return caesar_cipher_encode(text, -shift)

# Function to check if a number is prime
def is_prime(num):
    if num <= 1:
        return False
    for i in range(2, int(num**0.5) + 1):
        if num % i == 0:
            return False
    return True

# Main function demonstrating the utilization of the above functionalities
if __name__ == '__main__':
    password_length = 10
    password = generate_password(password_length)
    print(f'Generated Password: {password}')

    text = 'PythonIsAwesome'
    shift = 5
    encoded_text = caesar_cipher_encode(text, shift)
    print(f'Encoded Text: {encoded_text}')
    decoded_text = caesar_cipher_decode(encoded_text, shift)
    print(f'Decoded Text: {decoded_text}')

    num = 29
    print(f'Is {num} a prime number? {is_prime(num)}')

Code Output:
