在这个截图中,可以看到有5个节点,对应源代码的5段代码片段,例如 ImportFrom代码 和 函数定义function define的代码。这5个节点还有其各自的子节点,例如assign节点的子节点是call类型的节点(如果是调用一个函数)。更多语法树的节点类型,可参考https://docs.python.org/3/library/ast.html 不同类型的节点其属性不一...
If no name is given, the function will print out “Hello World”. Otherwise, the user will get a personalized “Hello” response. Remember also that you can define one or more function parameters for your UDF. You’ll learn more about this when you tackle the Function Arguments section. ...
