在上面的示例中,我们首先创建了一个包含5个元素的列表my_list,然后使用get方法获取了第3个元素和索引超出范围的元素。可以看到,当索引在列表范围内时,get方法返回对应的元素值;当索引超出范围时,get方法返回None。 列表list的get方法流程图 下面是列表list的get方法的流程图示意图: Index in rangeIndex out of ran...
首先定义API接口和参数,然后在后端代码中获取并处理参数,最后在前端代码中调用接口并传递参数。 以下为整个过程的序列图: 后端前端后端前端GET /api/list?data=1&data=2&data=3['1', '2', '3'] 这样,我们就成功实现了"get传list参数python"的功能,小白开发者可以按照上述步骤来进行实现。
