如何根据书名聚合python列表或字典中的值？

books = [
    {"书名": "Python入门教程", "值": 10},
    {"书名": "Python编程实战", "值": 20},
    {"书名": "Python高级编程", "值": 30},
    {"书名": "Python数据分析", "值": 40},
    {"书名": "Python机器学习", "值": 50}
]

aggregated_values = {}

for book in books:
    book_name = book["书名"]
    value = book["值"]
    
    if book_name in aggregated_values:
        aggregated_values[book_name] += value
    else:
        aggregated_values[book_name] = value

print(aggregated_values)

{'Python入门教程': 10, 'Python编程实战': 20, 'Python高级编程': 30, 'Python数据分析': 40, 'Python机器学习': 50}
