Question

  Substitute multiple whitespace with single whitespace in Python

如何在python中将多个空格压缩为1个空格？

例如，假设我有一个字符串

"some   user entered     text"

我想要成为

"some user entered text"

Answer 1

' '.join("some   user entered     text".split())

Answer 2

>>> import re
>>> re.sub("\s+"," ","some   user entered     text")
'some user entered text'
>>> 

编辑：

这也将取代换行符和标签等。

如果您特别想要空格/标签，可以使用

>>> import re
>>> re.sub("[ \t]+"," ","some   user entered     text")
'some user entered text'
>>> 

Answer 3

您可以使用以下内容：

text = 'sample base     text with multiple       spaces'

' '.join(x for x in text.split() if x)

OR：

text = 'sample base     text with multiple       spaces'
text = text.strip()
while '  ' in text:
    text = text.replace('  ', ' ')

Answer 4

>>> re.sub(r'\s+', ' ', 'ala   ma\n\nkota')
'ala ma kota'
