이 프로젝트로 모든 Python 기초를 다루세요 | 퀴즈부터 비밀번호 관리자까지.

Membuat projek ialah cara terbaik untuk mengambil apa yang anda pelajari dan melaksanakannya. Walaupun projek ini kelihatan mudah dan mudah, ia memainkan peranan penting dalam membina asas yang kukuh dalam pengaturcaraan Python. Saya telah mencipta projek ini untuk merangkumi kebanyakan asas dalam Python, memastikan sesiapa sahaja boleh mempelajari dan meningkatkan kemahiran pengekodan mereka melalui latihan praktikal.

1. Permainan Kuiz

Apakah itu? Permainan kuiz mudah di mana komputer bertanya soalan dan pemain menjawabnya.

Konsep yang digunakan:

• Senarai dan tupel
• Modul rawak
• Gelung
• Pernyataan bersyarat
• Pengendalian input pengguna
• Penjejakan skor

Cara ia berfungsi: Permainan bermula dengan mengalu-alukan pemain dan bertanya sama ada mereka mahu bermain. Ia kemudian membentangkan satu siri soalan rawak daripada senarai yang telah ditetapkan. Jawapan pemain disemak, dan markah mereka dikemas kini dengan sewajarnya. Permainan ini memberikan maklum balas pada setiap jawapan dan memaparkan markah akhir pada penghujungnya.

import random  # Import the random module for shuffling

print("Welcome to the Quiz Game")  # Print welcome message
wanna_play = input("Do you want to play the game (yes/no): ").lower()  # Ask if the user wants to play
if wanna_play != 'yes':  # If user does not want to play, quit
    quit()
print("Okay, then! Let's play")  # Print message to start the game

# Creating a list of tuples containing questions and answers 
question_answer_pairs = [
    ("What does CPU stand for?", "Central Processing Unit"),
    ("Which programming language is known as the 'mother of all languages'?", "C"),
    ("What does HTML stand for?", "HyperText Markup Language"),
    # ... (more questions)
]

# Shuffle the list of tuples to ensure random order
random.shuffle(question_answer_pairs)

score = 0

# Iterate through the shuffled list of tuples 
for question, correct_answer in question_answer_pairs:
    user_answer = input(f"{question} ").strip()  # Ask the question and get user input
    if user_answer.lower() == correct_answer.lower():  # Check if the answer is correct
        print("Correct answer")
        score += 1  # Increase score for a correct answer
    else:
        print(f"Incorrect answer. The correct answer is: {correct_answer}")
        score -= 1  # Decrease score for an incorrect answer
    print(f"Current Score: {score}")

# Print the final score
print(f"Quiz over! Your final score is {score}/{len(question_answer_pairs)}")

2. Permainan Teka Nombor (Teka Komputer)

Apakah itu? Permainan meneka nombor di mana komputer cuba meneka nombor yang dipilih oleh pengguna.

Konsep yang digunakan:

• Fungsi
• Gelung
• Pernyataan bersyarat
• Pengendalian input pengguna
• Algoritma carian binari

Cara ia berfungsi: Pengguna mentakrifkan julat dan memilih nombor dalam julat itu. Komputer kemudiannya menggunakan pendekatan carian binari untuk meneka nombor, dengan pengguna memberikan maklum balas sama ada tekaan itu terlalu tinggi, terlalu rendah atau betul. Permainan diteruskan sehingga komputer meneka dengan betul atau menentukan bahawa nombor itu berada di luar julat yang ditentukan.

def guess_number():
    """
    Function where the computer attempts to guess a number chosen by the user within a specified range.

    The user defines the lower and upper bounds of the range and provides a number for the computer to guess.
    The computer uses a binary search approach to guess the number and the user provides feedback to guide it.
    """
    # Get the lower bound of the range from the user
    low = int(input("Enter the lower range: "))
    # Get the upper bound of the range from the user
    high = int(input("Enter the higher range: "))

    # Check if the provided range is valid
    if low >= high:
        print("Invalid range. The higher range must be greater than the lower range.")
        return  # Exit the function if the range is invalid

    # Get the number from the user that the computer will attempt to guess
    Your_number = int(input(f"Enter your number for the computer to guess between {low} and {high}: "))

    # Check if the number entered by the user is within the specified range
    if Your_number < low or Your_number > high:
        print("The number you entered is out of the specified range.")
        return  # Exit the function if the number is out of the range

    # Initialize the computer's guess variable
    computer_guess = None

    # Loop until the computer guesses the correct number
    while computer_guess != Your_number:
        # Compute the computer's guess as the midpoint of the current range
        computer_guess = (low + high) // 2
        print(f"The computer guesses: {computer_guess}")

        # Get feedback from the user about the computer's guess
        feedback = input(f"Is {computer_guess} too low, too high, or correct? (Enter 'h' for higher, 'l' for lower, 'c' for correct): ").strip().lower()

        # Process the user's feedback to adjust the guessing range
        if feedback == 'c':
            if computer_guess == Your_number:
                print("The computer guessed your number correctly! Congrats!")
                return  # Exit the function once the correct number is guessed
            else:
                continue  
        elif feedback == 'h':
            high = computer_guess - 1  # If the guess is too high, lower the upper range
        elif feedback == 'l':
            low = computer_guess + 1  # If the guess is too low, increase the lower range
        else:
            print("Invalid feedback, please enter 'h', 'l', or 'c'.")  # Handle invalid feedback

# Call the function to start the guessing game
guess_number()

3. Permainan Teka Nombor (Teka Pengguna)

Apakah itu? Permainan meneka nombor di mana pengguna cuba meneka nombor yang dijana secara rawak.

Konsep yang digunakan:

• Fungsi
• Modul rawak
• Gelung
• Pernyataan bersyarat
• Pengendalian pengecualian
• Pengesahan input pengguna

Cara ia berfungsi: Komputer menjana nombor rawak dalam julat yang ditentukan. Pengguna kemudian membuat tekaan, dan program memberikan maklum balas sama ada tekaan itu terlalu tinggi atau terlalu rendah. Permainan diteruskan sehingga pengguna meneka nombor yang betul atau memutuskan untuk berhenti.

import random  # Import the random module to use its functions for generating random numbers

def guess_random_number(number):
    """
    Function to allow the user to guess a random number between 1 and the specified `number`.
    This function generates a random integer between 1 and the provided `number` (inclusive).
    It then repeatedly prompts the user to guess the random number, providing feedback on whether
    the guess is too high or too low, until the correct number is guessed. The function handles
    invalid inputs by catching exceptions and informing the user to enter a valid integer.
    """
    # Generate a random number between 1 and the specified `number` (inclusive)
    random_number = random.randint(1, number)
    guess = None  # Initialize the variable `guess` to None before starting the loop

Konsep yang digunakan:

• Mengimport modul
• Pilihan rawak daripada senarai
• Manipulasi rentetan
• Gelung
• Pernyataan bersyarat
• Pemahaman senarai

Cara ia berfungsi: Permainan memilih perkataan rawak daripada senarai yang telah ditetapkan. Pemain kemudian meneka huruf satu demi satu. Tekaan yang betul mendedahkan kedudukan huruf dalam perkataan, manakala tekaan yang salah mengurangkan baki nyawa pemain. Permainan tamat apabila pemain meneka keseluruhan perkataan atau kehabisan nyawa.

import random
from word_list import words  # Import the words from word_list.py file

def hangman():
    random_word = random.choice(words)  # Generate the random word
    print(random_word)  # Print the chosen word for testing purposes; remove in production

        if user_choice == computer_choice:
            print("It's a tie.")  # It's a tie if both choices are the same.
        elif _iswinner(user_choice, computer_choice):
            print("You won!")  # The user wins if their choice beats the computer's choice.
        else:
            print("You lost.")  # The user loses if the computer's choice beats theirs.

        # Ask the user if they want to play again.
        play_again = input("Do you want to play again? Enter 'yes' or 'no': ").strip().lower()

        # If the user doesn't enter 'yes', end the game.
        if play_again != 'yes':
            print("Thank you for playing!")  # Thank the user for playing.
            break  # Exit the loop and end the game.

def _iswinner(user, computer):
    # Determine if the user's choice beats the computer's choice.
    # Rock ('r') beats Scissors ('s'), Scissors ('s') beat Paper ('p'), Paper ('p') beats Rock ('r').
    if (user == "r" and computer == "s") or (user == "p" and computer == "r") or (user == "s" and computer == "p"):

7. Pengurus Kata Laluan

Apakah itu? Pengurus kata laluan mudah yang membolehkan pengguna menyimpan dan mendapatkan semula kata laluan yang disulitkan.

Concepts used:

• File I/O operations
• Encryption using the cryptography library
• Functions
• Exception handling
• User input handling
• Loops

How it works: The program uses the Fernet symmetric encryption from the cryptography library to securely store passwords. Users can add new passwords or view existing ones. Passwords are stored in an encrypted format in a text file, and decrypted when viewed.

from cryptography.fernet import Fernet

# The write_key function generates an encryption key and saves it to a file.
# It's currently commented out, but you need to run it once to create the 'key.key' file.
'''
def write_key():
    key = Fernet.generate_key()
    with open("key.key", "wb") as key_file:
        key_file.write(key)
'''

def load_key():
    """This function loads the encryption key from the 'key.key' file."""
    file = open("key.key", "rb")
    key = file.read()
    file.close()
    return key

# Load the key and create a Fernet object
key = load_key()
fer = Fernet(key)

def view():
    """Function to view stored passwords in the 'passwords.txt' file"""
    with open('passwords.txt', 'r') as f:
        for line in f.readlines():
            data = line.rstrip()
            user, passw = data.split("|")
            decrypted_password = fer.decrypt(passw.encode()).decode()
            print("User:", user, "| Password:", decrypted_password)

def add():
    """Function to add new account names and passwords to the 'passwords.txt' file"""
    name = input('Account Name: ')
    pwd = input("Password: ")
    with open('passwords.txt', 'a') as f:
        encrypted_password = fer.encrypt(pwd.encode()).decode()
        f.write(name + "|" + encrypted_password + "\n")

# Main loop to ask the user what they want to do: view passwords, add new passwords, or quit
while True:
    mode = input(
        "Would you like to add a new password or view existing ones (view, add), press q to quit? ").lower()

    if mode == "q":
        break
    if mode == "view":
        view()
    elif mode == "add":
        add()
    else:
        print("Invalid mode.")
        continue
