Python基础---函数 一.函数function 1.什么是函数 函数是组织好的,可重复使用的,用来实现单一,或相关联功能的代码段。 函数能提高应用的模块性,和代码的重复利用率。 2.函数的定义 语法: deffunctionname( parameters ):"函数_文档字符串"function_suitereturn[expression] 说明: 函数的名字就是语句块的名称 函数...

The final version of the function doesn`t display anything when it runs;it only returns a value.The print statements we wrote are useful for debugging,but once you get the function working,you should remove them.Code like that is called scaffolding because it is helpful for building the progr...

min:返回可迭代对象的最小值(可加key,key为函数名,通过函数的规则,返回最小值)。 I. 将iterable的每一个元素当作函数的参数传给函数,字典中,元素是键 II.按照函数的返回值进行比较大小 III. 返回的是遍历的元素x,即传入函数的参数 min([1,-2,3,-4,5])#-4min([1,-2,3,-4,5],key=abs)#按照绝...

Before we get to turning some of our existing code into a function, let’s spend a moment looking at the anatomy ofanyfunction in Python. Once this introduction is complete, we’ll look at some of our existing code and go through the steps required to turn it into a function that you...
