python按参考文献标题排序

以下是按参考文献标题排序的Python代码示例：

# 假设有一个包含参考文献信息的列表
references = [
    {"author": "Smith, J.", "title": "A Study of Mathematics", "year": 2005},
    {"author": "Brown, A.", "title": "The History of Art", "year": 2010},
    {"author": "Lee, K.", "title": "Introduction to Physics", "year": 2008}
]

# 使用sorted函数和lambda表达式按标题排序
sorted_references = sorted(references, key=lambda x: x["title"])

# 打印排序后的参考文献列表
for ref in sorted_references:
    print(ref["title"], ",", ref["author"], ",", ref["year"])

输出结果：

A Study of Mathematics , Smith, J. , 2005
Introduction to Physics , Lee, K. , 2008
The History of Art , Brown, A. , 2010

该代码使用lambda表达式作为key函数来指定排序依据，按照参考文献标题进行排序，并打印排序后的参考文献列表。
