map(function, iterable, …) 参数说明: function – 函数 iterable – 一个或多个序列 def test(x): return x * x # 注意:在python3中返回的并不是一个列表,而是一个map迭代器对象。需要使用list()方法将它转化为列表 res = map(test,[1,2,3]) ...
一、Python map()函数的用法 map(function, iterable) 功能:遍历序列,对序列中每个元素进行操作,最终获取新的序列。 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 i = [11, 22, 33, 44, 55] map(函数,可迭代的对象(可以for循环的东西)) def f2(a): return a + 100 ...
