codeRose Python(六) 高阶函数 1.map/reduce map()函数接收两个参数,一个是函数,一个是Iterable,map将传入的函数依次作用到序列的每个元素,并把结果作为新的Iterator返回。 把函数f(x)=x*x作用于一个list序列 deff(x):returnx*x r=map(f,[1,2,3,4,5,6])print(list(r)) 控制台输出结果: [1, 4...
Python(一)函数 在Python中,定义一个函数用def语句,依次些函数名、括号、括号中的参数和冒号:,然后在缩进块中编写函数体,函数的返回值用return语句返回。 1.自定义函数 自定义一个比较两个数大小的函数,返回最大值。 defmaxnum(x,y):ifx>y:returnxelifx==y:return'两数相等'else:returnyprint(maxnum(2,2...
