在Python中使用文本文件创建嵌套字典函数

def create_nested_dict_from_text_file(file_path):
    nested_dict = {}
    with open(file_path, 'r') as file:
        lines = file.readlines()
        for line in lines:
            key, value = line.strip().split(':')
            keys = key.split('.')
            current_dict = nested_dict
            for i in range(len(keys) - 1):
                if keys[i] not in current_dict:
                    current_dict[keys[i]] = {}
                current_dict = current_dict[keys[i]]
            current_dict[keys[-1]] = value
    return nested_dict

person.name: John
person.age: 30
person.address.city: New York
person.address.zip: 12345

nested_dict = create_nested_dict_from_text_file('data.txt')
print(nested_dict)

{
    'person': {
        'name': 'John',
        'age': '30',
        'address': {
            'city': 'New York',
            'zip': '12345'
        }
    }
}
