Rake.split_sentences(text) uses 'u' as separator

[xyutech]

Hello,
I met an issue that split_sentences(text) function uses 'u' as separator. For instance
text: "is an incredibly popular library and for good reason it s powerful fast"
sentences list: [u'is an incredibly pop', u'lar library and for good reason it s powerf', u'l fast']
Definitely I can fix it at my environment, but I wonder what I did wrong and why nobody met this issue before?
My environment is python 2.7, python-rake is installed with pip.

That just means the strings are being represented as unicode strings. '' is an ascii string in python 2.7 and u'' is a unicode string. They work the same as normal strings, details here:
https://docs.python.org/2/howto/unicode.html

That idiosyncrasy is one of the thing's cleaned up in python 3.x by the way, and one major reason it's recommended to use instead of python 2.7. I used unicode strings specifically because they're more robust and notably support more languages, and this is a multilingual library. Tell me if these are actually causing problems for you, but they shouldn't. Closed.

Thank you for you reply.
Just let me add some more info to make sure that we are on the same page. I did not tell about notation
u'is an incredibly pop'
It is clear. My issue was about input string was separated by 'u'. So input is:
is an incredibly popular library and for good reason it s powerful fast
and separation is
is an incredibly pop | lar library and for good reason it s powerf | l fast

Got the same Problem - 'restaurant' is being split into 'resta' and 'rant'...
