python - 如何删除列表中的空格？

Question

我有一条短信:

text = '''
    Wales greatest moment. Lille is so close to the Belgian 
    border, 
    this was essentially a home game for one of the tournament favourites. Their 
    confident supporters mingled with their new Welsh fans on the streets, 
    buying into the carnival spirit - perhaps more relaxed than some might have 
    been before a quarter-final because they thought this was their time.
    In the driving rain, Wales produced the best performance in their history to 
    carry the nation into uncharted territory. Nobody could quite believe it.'''

我有一个代码:

 words = text.replace('.',' ').replace(',',' ').replace('\n',' ').split(' ')
    print(words)

和输出:

['Wales', 'greatest', 'moment', '', 'Lille', 'is', 'so', 'close', 'to', 'the', 'Belgian', 'border', '', '', 'this', 'was', 'essentially', 'a', 'home', 'game', 'for', 'one', 'of', 'the', 'tournament', 'favourites', '', 'Their', '', 'confident', 'supporters', 'mingled', 'with', 'their', 'new', 'Welsh', 'fans', 'on', 'the', 'streets', '', '', 'buying', 'into', 'the', 'carnival', 'spirit', '-', 'perhaps', 'more', 'relaxed', 'than', 'some', 'might', 'have', '', 'been', 'before', 'a', 'quarter-final', 'because', 'they', 'thought', 'this', 'was', 'their', 'time', '', 'In', 'the', 'driving', 'rain', '', 'Wales', 'produced', 'the', 'best', 'performance', 'in', 'their', 'history', 'to', '', 'carry', 'the', 'nation', 'into', 'uncharted', 'territory', '', 'Nobody', 'could', 'quite', 'believe', 'it', '']

你可以看到，列表有空格，我删除了'\n', ',' and '.'.

但现在我不知道如何删除这些空格。

Answer 1

您可以 filter他们，如果你不喜欢他们

no_empties = list(filter(None, words))

If function is None, the identity function is assumed, that is, all elements of iterable that are false are removed.

这是有效的，因为空元素被认为是错误的。
