The 'arbitrary argument' list is an another way to pass arguments to a function. In the function body, these arguments will be wrapped in a tuple and it can be defined with *args construct. Before this variable, you can define a number of arguments or no argument. Example: defsum(*numb...
If you define a function inside another function, then you’re creating aninner function, also known as a nested function. In Python, inner functions have direct access to the variables and names that you define in the enclosing function. This provides a mechanism for you to create helper fun...

It’s possible to define functions inside other functions. Such functions are called inner functions. Here’s an example of a function with two inner functions:Python inner_functions.py def parent(): print("Printing from parent()") def first_child(): print("Printing from first_child()")...
Function bodies often contain a return statement: def<name>(arg1, arg2,... argN): ...return<value> 2)def executes at runtime iftest:deffunc():#Define func this way...else:deffunc():#Or else this way... ... func()#Call the version selected and buil ...
In the above function, you ask the user to give a name. 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...
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...
method(方法)—— A function which is defined inside a class body. Ifcalled as an attribute of an instance of that class, the methodwill get the instance object as its first argument (which isusually called self). 从上面可以看出, 别的编程语言一样, Function也是包含一个函数头和一个函数体,...
