Defining Python functions: Syntax and naming rulesIn Python, you can define a function using the "def" keyword followed by the function name, parentheses containing optional parameters, and a colon. Function bodies, which contain the code to be executed when the function is called, are indented...
In Python the return statement (the word return followed by an expression.) is used to return a value from a function, return statement without an expression argument returns none. See the syntax. def function_name(argument1, argument2, ...) : statement_1 statement_2 ... return expression...

I will use these conventions shortly in the discussion of function syntax, and will continue to use the conventions throughout the tutorial. 1.11.2.A First Function Definition#函数定义 If you know it is the birthday of a friend, Emily, you might tell those gathered with you to sing “Happy...
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. ...
You apply the function_name decorator to the method to define the function name, while the HTTP endpoint is set by applying the route decorator. This example is from the HTTP trigger template for the Python v2 programming model, where the binding parameter name is req. It's the sample code...
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...
I speak, of course, of the traditional function. (Python also supports classes, of course, but much of that should be easy to pick up once you understand the function syntax.) Predefined Functions First things first: Unlike many of its object-oriented contemporaries, Python supports (and ...
