Sometimes, we do not know in advance the number of arguments that will be passed into a function. Python allows us to handle this kind of situation through function calls with an arbitrary number of arguments. I
函数调用(function call)方式:函数名(表达式); 调用函数时括号里的表达式称为实参(argument); 函数“接受”(accept)实参(有的话)后返回(return)得到一个结果即返回值(return value); >>> type('Hello, World!') <class 'str'> 1. 2. Python提供了能够将值从一种类型转换为另一种类型的内建函数; 函数in...
Those tasks are read, process, and write. The main program now simply needs to call each of these in turn. Note: The def keyword introduces a new Python function definition. You’ll learn all about this very soon. In life, you do this sort of thing all the time, even if you don’...

function call 调用 python 代码 Python函数调用本质上是将程序执行流程转移到指定内存地址的过程。在解释器执行def语句时会创建函数对象，其中保存了字节码和上下文信息。当调用函数时，Python虚拟机（PVM）会创建新的栈帧，用于存储局部变量和执行环境。参数传递机制采用"对象引用传递"。调用函数时，实参实际上是传递对象...
