You likely don’t need to know about this in your first week of using Python, but as you dive deeper into Python you’ll find that it can be quite convenient to understand how to pass a function into another fu
Python allows you to pass a function as an argument to another function which helps you to write flexible and reusable code.Passing a function as an argumentYou can pass a function as an argument by defining two functions and passing one function as a parameter when calling the other....

reduce与map函数一样,也属于高阶函数,其原型为reduce(function,sequence),作用是用function对序列进行累计操作,返回的是一个累计值。累计操作不是计数操作,而是对列表里第一个数、第二个数传入function里处理,如function函数为lamda x,y:x+y,即对数x和y相加操作,接下来是使用该结果与第三个数相加,这样来调用funct...

def functionName(params): # 假如这个函数就是输出欢迎光临 print('欢迎光临') 函数使用:函数名 + () 借用菜鸟教程的一张图来更加形象的解释 def 是defnie定义的意思,max呢就是函数名称,通常函数名要与函数功能一致,这样看代码的人就能秒懂这个函数是干啥的,一对括号括起来呢是固定语法,括号内可以有参数也...
