if key_to_check in data_dict: print(f"The key '{key_to_check}' exists in the JSON data.") else: print(f"The key '{key_to_check}' does not exist in the JSON data.") 在这个例子中,我们首先导入了json模块,然后定义了一个包含JSON数据的字符串json_data。接着,我们使用json.loads()函数...
data = json.loads(json_data) 4. 使用in关键字检查json数据中是否存在指定的key 由于我们已经将JSON数据转换为了Python字典,因此可以直接使用in关键字来检查指定的key是否存在。 python key_to_check = "name" if key_to_check in data: print(f"Key '{key_to_check}' exists in the JSON data.") els...
