推荐答案

6的答案是远远不够的为OP可以很容易地通过试验的的间preTER ：

6 answers is not nearly enough for a question that OP could easily have answered himself by testing in the interpreter:

>>> "42 0".split()  # or .split(" ")
['42', '0']

答：是的，

但它没有被明确指出，拆分通过在空白默认分裂（空格，制表符的回车的和的换行符）如果你不提供的参数吧。

But it has not been specifically pointed out that the split method by default splits on whitespace (space, tab, carriage return and newline) if you do not supply an argument to it.

>>> " \r  42\n\r \t\n   \r0\n\r\n".split()
['42', '0']

此外，使用地图当你想iterables的项目内建转换如 INT ，浮动， STR 等。

Also, using map usually looks cleaner than using list comprehensions when you want to convert the items of iterables to built-ins like int, float, str, etc.:

>>> map(int, "42 0".split())
[42, 0]
