在嵌套字典中从另一个字典键值对进行更新

def update_nested_dict(dict1, dict2):
    for key, value in dict2.items():
        if key in dict1 and isinstance(dict1[key], dict) and isinstance(value, dict):
            update_nested_dict(dict1[key], value)
        else:
            dict1[key] = value

# 示例用法
dict1 = {'a': 1, 'b': {'c': 2, 'd': {'e': 3}}}
dict2 = {'b': {'c': 4, 'd': {'f': 5}}, 'g': 6}

update_nested_dict(dict1, dict2)
print(dict1)

{'a': 1, 'b': {'c': 4, 'd': {'e': 3, 'f': 5}}, 'g': 6}
