Python新手必备：5个实用迷你项目源码解析（建议收藏）

一、引言

作为Python新手，通过实践小项目来巩固所学知识是非常有帮助的。本文将介绍5个实用的Python迷你项目，并提供源码解析。这些项目不仅可以帮助你提升编程技能，还能让你更好地懂得Python的应用。

二、项目一：计算器

这个项目是一个明了的命令行计算器，赞成加、减、乘、除四种基本运算。


# 计算器项目源码
def add(x, y):
    return x + y
def subtract(x, y):
    return x - y
def multiply(x, y):
    return x * y
def divide(x, y):
    if y == 0:
        return "Error! Division by zero."
    return x / y
def calculator():
    while True:
        print("Options:")
        print("Enter 'add' for addition")
        print("Enter 'subtract' for subtraction")
        print("Enter 'multiply' for multiplication")
        print("Enter 'divide' for division")
        print("Enter 'quit' to end the program")
        user_input = input(": ")
        if user_input == "quit":
            break
        elif user_input in ('add', 'subtract', 'multiply', 'divide'):
            num1 = float(input("Enter first number: "))
            num2 = float(input("Enter second number: "))
            if user_input == 'add':
                print("The result is:", add(num1, num2))
            elif user_input == 'subtract':
                print("The result is:", subtract(num1, num2))
            elif user_input == 'multiply':
                print("The result is:", multiply(num1, num2))
            elif user_input == 'divide':
                print("The result is:", divide(num1, num2))
        else:
            print("Unknown command")
if __name__ == "__main__":
    calculator()

三、项目二：待办事项列表

这个项目是一个明了的待办事项列表，用户可以添加、删除和查看待办事项。


# 待办事项列表项目源码
todo_list = []
def show_todo_list():
    print("Todo List:")
    for index, item in enumerate(todo_list, start=1):
        print(f"{index}. {item}")
def add_todo_item():
    item = input("Enter a new todo item: ")
    todo_list.append(item)
    print("Item added successfully.")
def remove_todo_item():
    show_todo_list()
    try:
        index = int(input("Enter the number of the item to remove: ")) - 1
        if index >= 0 and index < len(todo_list):
            removed_item = todo_list.pop(index)
            print(f"Item '{removed_item}' removed successfully.")
        else:
            print("Invalid index. Please try again.")
    except ValueError:
        print("Invalid input. Please enter a number.")
def todo_list_manager():
    while True:
        print(" Options:")
        print("1. Show Todo List")
        print("2. Add Todo Item")
        print("3. Remove Todo Item")
        print("4. Quit")
        choice = input(": ")
        if choice == '1':
            show_todo_list()
        elif choice == '2':
            add_todo_item()
        elif choice == '3':
            remove_todo_item()
        elif choice == '4':
            break
        else:
            print("Invalid choice. Please try again.")
if __name__ == "__main__":
    todo_list_manager()

四、项目三：数字猜谜游戏

这个项目是一个明了的数字猜谜游戏，玩家需要猜测一个随机生成的数字。


# 数字猜谜游戏项目源码
import random
def guess_number_game():
    number_to_guess = random.randint(1, 100)
    attempts = 0
    print("Welcome to the Guess the Number Game!")
    print("I'm thinking of a number between 1 and 100.")
    while True:
        try:
            user_guess = int(input("Enter your guess: "))
            attempts += 1
            if user_guess < number_to_guess:
                print("Too low, try again.")
            elif user_guess > number_to_guess:
                print("Too high, try again.")
            else:
                print(f"Congratulations! You guessed the number in {attempts} attempts.")
                break
        except ValueError:
            print("Please enter a valid integer.")
if __name__ == "__main__":
    guess_number_game()

五、项目四：Web服务器

这个项目是一个明了的Web服务器，使用Python的内置HTTP服务器模块。


# Web服务器项目源码
import http.server
import socketserver
PORT = 8000
Handler = http.server.SimpleHTTPRequestHandler
with socketserver.TCPServer(("", PORT), Handler) as httpd:
    print(f"Serving at port {PORT}")
    httpd.serve_forever()

六、项目五：数据可视化

这个项目使用Python的matplotlib库来绘制明了的数据图表。


# 数据可视化项目源码
import matplotlib.pyplot as plt
# 数据
categories = ['Category A', 'Category B', 'Category C', 'Category D']
values = [10, 20, 30, 40]
# 创建柱状图
plt.bar(categories, values)
# 添加标题和标签
plt.title('Bar Chart Example')
plt.xlabel('Categories')
plt.ylabel('Values')
# 显示图表
plt.show()
