How to Split Chinese Character with backslash representation?

Hi all,

I was trying to split a string that
represent chinese characters below:

???['\xc5\xeb\xc7\xd5\xbc']

But why the split function here doesn't seem
to do the job for obtaining the desired result:

['\xc5','\xeb','\xc7','\xd5','\xbc']

¼'\xd5''\xeb\xc7'

Basically, you characters are already separated into a list of
characters, that's effectively what a string is (but with a few more
methods applicable only to lists of characters, not to other lists).

re: How to Split Chinese Character with backslash representation?

Thanks but my intention is to strictly use regex.
Since there are separator I need to include as delimiter
Especially for the case like this:
['\xc5', '\xeb', '\xc7', '\xd5', '\xbc', '-', '-', 'F', 'O', 'O', '-', '-','B', 'A', 'R']

What we want as the output is this instead:
['\xc5', '\xeb', '\xc7', '\xd5', '\xbc','FOO','BAR]

What's the best way to do it?

last two elements in his desired list. I'm still puzzling this one...

the RE matches either a sequence of latin characters, *or* a single
non-ASCII character.

you may want to adjust the character ranges to match the encoding you're
using, and your definition of non-chinese words.

news:mailman.1319.1161920633.11739.python-list@python.org...There are no backslash characters in the string str, so split finds nothing
to split on. I know it looks like there are, but the backslashes shown are
part of the \x escape sequence for defining characters when you can't or
don't want to use plain ASCII characters (such as in your example in which
the characters are all in the range 0x80 to 0xff). Look at this example:
@

I defined s using the escaped \x notation, but s does not contain any
backslashes, it contains the '@' character, whose ordinal character value is
64, or 40hex.

Also, str is not the best name for a string variable, since this masks the
built-in str type.

r'raw_string', you are in fact splitting on TWO backslashes. It looks
like you want to treat str as a raw string to get at the slashes, but it
isn't a raw string and I don't think you can directly convert it to one.
If you want the numeric values of each byte, you can do the following:

Py >>char_values = [ ord(c) for c in str ]
Py >>char_values
[ 197, 235, 199, 213, 188 ]
Py >>>

Note that those numbers are decimal equivalents of the hex values given
in your string, but are now in integer format.

On the other hand, you may want to use str.encode('gbk') (or whatever
your encoding is) so that you're actually dealing with characters rather
than bytes:

Py >>str.decode('gbk')

Traceback (most recent call last):
File "<pyshell#29>", line 1, in -toplevel-
str.decode('gbk')
UnicodeDecodeError: 'gbk' codec can't decode byte 0xbc in position 4:
incomplete multibyte sequence
Py >>str[0:4].decode('gbk')
u'\u70f9\u94a6'

Py >>print str[0:4].decode('gbk')
烹钦
Py >>print str[0:4]
ÅëÇÕ

OK, so gbk choked on the odd character at the end. Maybe you need a
different encoding, or maybe your string got truncated somewhere along
the line....
