How to remove this \xa0 from a string in python?
提问by slopeofhope
I have the following string:
我有以下字符串：
word = u'Buffalo,\xa0IL\xa060625'
I don't want the "\xa0" in there. How can I get rid of it? The string I want is:
我不想要“\xa0”在那里。我怎样才能摆脱它？我想要的字符串是：
word = 'Buffalo, IL 06025

If you know for sure that is the only character you don't want, you can .replaceit:
如果您确定这是唯一不想要的角色，您可以.replace：
>>> word.replace(u'\xa0', ' ')
u'Buffalo, IL 60625'
If you need to handle all non-ascii characters, encoding and replacing bad characters might be a good start...:
如果您需要处理所有非 ascii 字符，编码和替换坏字符可能是一个好的开始...：
>>> word.encode('ascii', 'replace')
'Buffalo,?IL?60625'

This seems to work for getting rid of non-ascii characters:
这似乎适用于摆脱非 ascii 字符：
fixedword = word.encode('ascii','ignore')

There is no \xathere. If you try to put that into a string literal, you're going to get a syntax error if you're lucky, or it's going to swallow up the next attempted character if you're not, because \xsequences aways have to be followed by two hexadecimal digits.
那里没有\xa。如果您尝试将其放入字符串文字中，那么幸运的话您将得到一个语法错误，否则它将吞掉下一个尝试的字符，因为\x必须在序列离开之后两个十六进制数字。
What you have is \xa0, which is an escape sequence for the character U+00A0, aka "NO-BREAK SPACE".
您拥有的是\xa0，这是字符U+00A0的转义序列，又名“NO-BREAK SPACE”。
I think you want to replace them with spaces, but whatever you want to do is pretty easy to write:
我认为您想用空格替换它们，但是无论您想做什么都很容易编写：
word.replace(u'\xa0', u' ') # replaced with space
word.replace(u'\xa0', u'0') # closest to what you were literally asking for
word.replace(u'\xa0', u'') # removed completely

The most robust way would be to use the unidecodemoduleto convert all non-ASCII characters to their closest ASCIIequivalent automatically.
最可靠的方法是使用该unidecode模块将所有非 ASCII 字符自动转换为最接近的ASCII 字符。
The character \xa0(not \xaas you stated) is a NO-BREAK SPACE, and the closest ASCII equivalent would of course be a regular space.
这个字符\xa0（不是\xa你说的）是一个NO-BREAK SPACE，最接近的 ASCII 等价物当然是一个普通的空格。
import unidecode
word = unidecode.unidecode(word)

You can easily use unicodedatato get rid of all of \x...characters.
您可以轻松地使用unicodedata来摆脱所有\x...字符。
from unicodedata import normalize
normalize('NFKD', word)
>>> 'Buffalo, IL 60625'
