如何减去两个字符串？ [英] How to subtract two strings?

问题描述

我有一个长字符串，基本上是一个类似于 str = lamp，bag，mirror （和其他项目）

I have a long string, which is basically a list like str="lamp, bag, mirror," (and other items)

我想知道是否可以通过其他编程语言轻松地添加或减去某些项目： str = str- bag， 并得到 str = lamp，mirror， 在python中不起作用（我在W8 pc上使用2.7）

I was wondering if I can add or subtract some items, in other programming languages I can easily do: str=str-"bag," and get str="lamp, mirror," this doesnt work in python (I'm using 2.7 on a W8 pc)

是否可以将字符串拆分成 bag，并以某种方式将其用作减法？然后我仍然需要弄清楚如何添加。

Is there a way to split the string across say "bag," and somehow use that as a subtraction? Then I still need to figure out how to add.

推荐答案

您也可以这样做

print "lamp, bag, mirror".replace("bag,","")
