You can also use a regular expression to match whitespace characters and remove them using there.sub()function. This example uses the following file,regexspaces.py, to show some ways you can use regex to remove whitespace characters: regexspaces.py importre s=' Hello World From DigitalOcean \...

filter(function,list),把list中的元素一个个丢到function中。Return True的元素组成一个new list。 ll = [1,2,3,4,5] def func(x): return x % 2 != 0 print filter(func,ll) 说下lambda吧: 匿名函数,lambda a:b,当中a表示參数。b表示返回值。

也就是说假如模块A中有函数function( ),在模块B中也有函数function( ),如果引入A中的function在先、B中的function在后,那么当调用function函数的时候,是去执行模块B中的function函数。 如果想一次性引入math中所有的东西,还可以通过from math import *来实现,但是不建议这么做。
