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。

The simplest method to get the shape of a list in Python is by using thelen()function. It provides the length (number of elements) of a list, effectively giving the size of the first dimension. Thelen()function has a simple and concise syntax: ...
Getting the number of elements in a list in Python is a common operation. For example, you will need to know how many elements the list has whenever you iterate through it. Remember that lists can contain a combination of types, like integers, floats, strings, booleans, other lists, etc...
