    words = ["python", "programming", "language", "computer", "science"]
    return random.choice(words)

def play_hangman(word):
    guessed = "_" * len(word)
    guessed_list = list(guessed)
    word_list = list(word)

    while "_" in guessed_list:
        guess = input("Guess a letter: ")
        if guess in word_list:
            for i in range(len(word_list)):
                if word_list[i] == guess:
                    guessed_list[i] = guess
        else:
            print("Incorrect guess!")
        print("".join(guessed_list))

    print("Congratulations! You guessed the word:", word)

word = get_random_word()
play_hangman(word)

Web scraper:

Build a simple web scraper that extracts specific data from a website. This project introduces learners to Python libraries like BeautifulSoup and requests, as well as basic web scraping techniques. In this example, we will scrape the titles of articles from the front page of a website (in this case, ‘https://codinginvaders.com/ds’) using the BeautifulSoup and requests libraries.

import requests
from bs4 import BeautifulSoup

url = 'https://codinginvaders.com/ds'
response = requests.get(url)
content = response.content

soup = BeautifulSoup(content, 'html.parser')
article_titles = soup.find_all('h2', class_='entry-title')

for i, title in enumerate(article_titles, start=1):
    print(f"{i}. {title.text.strip()}")

In this version, the code fetches the content from the given URL, parses it using BeautifulSoup, and extracts the article titles using the ‘h2’ tag and ‘entry-title’ class. It then prints the article titles in a numbered list format.

Tic-tac-toe:

Develop a simple text-based Tic-tac-toe game where two players can take turns placing their respective symbols (‘X’ and ‘O’) on a 3×3 grid. This project helps learners understand how to use nested loops, lists, and basic game logic in Python.

    print("   |   |   ")
    print(" " + board[0] + " | " + board[1] + " | " + board[2] + " ")
    print("___|___|___")
    print("   |   |   ")
    print(" " + board[3] + " | " + board[4] + " | " + board[5] + " ")
    print("___|___|___")
    print("   |   |   ")
    print(" " + board[6] + " | " + board[7] + " | " + board[8] + " ")
    print("   |   |   ")

# Check if a player has won
def check_win(board, player):
    if (board[0] == player and board[1] == player and board[2] == player) or \
       (board[3] == player and board[4] == player and board[5] == player) or \
       (board[6] == player and board[7] == player and board[8] == player) or \
       (board[0] == player and board[3] == player and board[6] == player) or \
       (board[1] == player and board[4] == player and board[7] == player) or \
       (board[2] == player and board[5] == player and board[8] == player) or \
       (board[0] == player and board[4] == player and board[8] == player) or \
       (board[2] == player and board[4] == player and board[6] == player):
        return True
    else:
        return False

# Main function to play the game
def play_game():
    # Initialize the board
    board = [" ", " ", " ", " ", " ", " ", " ", " ", " "]
    print_board(board)

    # Players and their symbols
    players = ["X", "O"]
    player_symbols = {}
    player_symbols[players[0]] = input("Enter name for Player 1 (symbol X): ")
    player_symbols[players[1]] = input("Enter name for Player 2 (symbol O): ")
    print("Let's start the game!")

    # Randomly select the player to go first
    current_player = players[random.randint(0, 1)]
    while True:
        print(player_symbols[current_player] + "'s turn.")
        position = int(input("Enter a position (1-9): ")) - 1
        if board[position] == " ":
            board[position] = current_player
            print_board(board)
            if check_win(board, current_player):
                print(player_symbols[current_player] + " has won!")
                break
            elif " " not in board:
                print("The game is a tie.")
                break
            else:
                current_player = players[0] if current_player == players[1] else players[1]
        else:
            print("That position is already taken. Please try again.")

if __name__ == "__main__":
    play_game()

Mini Projects Using Python

Mini projects using Python are more advanced than simple Python projects, but still manageable for beginners with a good understanding of the language. These projects can help learners solidify their programming skills while exploring various libraries and functionalities that Python offers. By working on mini projects, learners can apply Python concepts to real-world problems and develop practical solutions.

Examples of mini projects using Python:

File organizer:

Develop a file organizer that sorts files in a directory based on their extensions. This project introduces learners to Python’s os and shutil libraries and helps them understand file handling and directory manipulation.

import os
import shutil

def organize_files(directory):
    os.chdir(directory)

    for file in os.listdir():
        file_ext = file.split('.')[-1]

        if not os.path.exists(file_ext):
            os.mkdir(file_ext)

        shutil.move(file, file_ext)

directory = input("Enter the path of the directory you want to organize: ")
organize_files(directory)

Currency converter:

Create a currency converter that fetches the latest exchange rates from an API and converts an input amount between two currencies. This project introduces learners to API requests, JSON data manipulation, and Python’s requests library.

import requests

def get_exchange_rates(api_key):
    url = f"https://openexchangerates.org/api/latest.json?app_id={api_key}"
    response = requests.get(url)
    return response.json()["rates"]

def convert_currency(amount, from_currency, to_currency, rates):
    return amount * (rates[to_currency] / rates[from_currency])

api_key = "YOUR_API_KEY"
amount = float(input("Enter the amount you want to convert

Text-to-speech converter:

Build a simple text-to-speech converter that converts text input into speech output. This project helps learners understand how to use Python’s text-to-speech libraries, such as gTTS and pyttsx3.

from gtts import gTTS
import os

def text_to_speech(text):
    language = 'en'
    speech = gTTS(text=text, lang=language, slow=False)
    speech.save("output.mp3")
    os.system("mpg321 output.mp3")

text = input("Enter the text you want to convert to speech: ")
text_to_speech(text)

In this code, we use the gTTS library to convert the input text into speech and save it as an MP3 file. We then use the mpg321 library to play the MP3 file, which outputs the speech. This project can be expanded upon by allowing the user to select the language and speech rate.
