在python中使用重叠的键重命名字典中的键

def rename_keys(dictionary, old_key, new_key):
    new_dict = {new_key if key == old_key else key: value for key, value in dictionary.items()}
    return new_dict

# 示例用法
my_dict = {'key1': 'value1', 'key2': 'value2', 'key3': 'value3', 'key1': 'value4'}
new_dict = rename_keys(my_dict, 'key1', 'new_key')
print(new_dict)

{'new_key': 'value4', 'key2': 'value2', 'key3': 'value3'}
