从数组中的每个元素中删除最后一个字符(Python)

Question

我有一个数组find_words

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

我想删除所有'$'所以它看起来像

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

我该怎么做？另外,我如何重新添加'$'.

Answer 1

为此,您可以简单地用一个列表理解和str.rstrip():

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

或者添加它们:

[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$', 'Adjective$']
