Python练习代码

Python练习代码通常是用于巩固学习和提升编程技能的小规模项目或练习示例。它们涵盖了许多主题，例如数据结构、算法、函数、类等。下面是一个简单的例子，展示如何创建一个迷你图书管理系统：

class Book:
    def __init__(self, title, author):
        self.title = title
        self.author = author

class Library:
    def __init__(self):
        self.books = []

    def add_book(self, book):
        self.books.append(book)

    def search_by_title(self, title):
        return [book for book in self.books if book.title == title]

# 示例用法
book1 = Book("Python Crash Course", "Eric Matthes")
book2 = Book("Fluent Python", "Luciano Ramalho")

library = Library()
library.add_book(book1)
library.add_book(book2)

title_search = input("请输入书名查找：")
result = library.search_by_title(title_search)
if result:
    print(f"找到了以下书籍：")
    for book in result:
        print(book.title, " - ", book.author)
else:
    print("未找到匹配的书籍。")
