从每个元素的数组中删除最后一个字符（蟒蛇） [英] Removing last character from each element in array (Python)

问题描述

我有一个数组find_words这是

I have an array find_words which is

[u'Duration$', u'Noun$', u'Adjective$']

我想删除所有的$，因此它看起来像

I would like to remove all the '$' so it looks like

[u'Duration', u'Noun', u'Adjective']

我怎么去呢？此外，我怎么重新添加$为好。

How do I go about this? Also, how do I re-add the '$' as well.

推荐答案

您可以做到这一点简单地用<一个href=\"http://www.youtube.com/watch?v=t85uBptTDYY&list=UUAuqj5Bs5mTTl1mIVDmuAlw&index=1&feature=plcp\">list COM prehension 和 str.rstrip（） ：

You can do this simply with a list comprehension and str.rstrip():

[word.rstrip("$") for word in words]

或添加它们：

[word+"$" for word in words]

例如：

>>> words = ['Duration$', 'Noun$', 'Adjective$']
>>> words = [word.rstrip("$") for word in words]
>>> words
['Duration', 'Noun', 'Adjective']
>>> [word+"$" for word in words]
['Duration$', 'Noun$', 'Adjective$']
