如何重命名dict中的所有关键点？

def rename_dict_keys(dictionary, prefix):
    new_dict = {}
    for key in dictionary.keys():
        new_key = prefix + key  # 重命名关键字
        new_dict[new_key] = dictionary[key]  # 将原字典中对应关键字的值赋给新字典中的重命名后的关键字
    return new_dict

# 示例用法
my_dict = {'name': 'John', 'age': 25, 'gender': 'male'}
new_dict = rename_dict_keys(my_dict, 'new_')
print(new_dict)

{'new_name': 'John', 'new_age': 25, 'new_gender': 'male'}
