•filter(func, lst),将func作用于lst的每个元素,然后根据返回值是True或False判断是保留还是丢弃该元素。 下面看下Python高级函数使用 map的使用:map(function, iterable, ...) 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。 >>>...
根据提供的函数对指定序列做映射 语法map(function, iterable, …) 返回一个将function应用于iterable中每一项并输出其结果的迭代器 当有多个可迭代对象时,最短的可迭代对象耗尽则整个迭代就将结束 >>>def square(x) : # 计算平方数 ... return x ** 2 ... >>> map(square, [1,2,3,4,5]) # 计算...
