假设这个字符串:
The fox jumped over the log.
变成:
The fox jumped over the log.
在不分割和进入列表的情况下,最简单的实现方法(1-2行)是什么?

当前回答
最简单的解决方案!
a = 'The fox jumped over the log.'
while ' ' in a: a = a.replace(' ', ' ')
print(a)
输出:
The fox jumped over the log.
其他回答
类似于前面的解决方案,但更具体:用一个空格替换两个或多个空格:
>>> import re
>>> s = "The fox jumped over the log."
>>> re.sub('\s{2,}', ' ', s)
'The fox jumped over the log.'
def unPretty(S):
# Given a dictionary, JSON, list, float, int, or even a string...
# return a string stripped of CR, LF replaced by space, with multiple spaces reduced to one.
return ' '.join(str(S).replace('\n', ' ').replace('\r', '').split())
Foo是你的字符串:
" ".join(foo.split())
需要注意的是,这将删除“所有空白字符(空格,制表符,换行符,返回,formfeed)”(感谢hhsaffar,见评论)。例如,“这不是一个测试”将有效地以“这是一个测试”结束。
一个简单的灵魂
>>> import re
>>> s="The fox jumped over the log."
>>> print re.sub('\s+',' ', s)
The fox jumped over the log.
string = 'This is a string full of spaces and taps'
string = string.split(' ')
while '' in string:
string.remove('')
string = ' '.join(string)
print(string)
结果:
这是一个充满空格和点击的字符串
