For example  : when the input is "العربيه" the output is:"عرب" which is right answer but when the input is "كاتب" the output is:"ب", and when the input is "يخاف" the output is " خف".

When you're using Unicode with re in Python 2, you should include the
re.UNICODE flag. For example:

HARAKAT_pat = re.compile(ur"[" + u"".join([FATHATAN, DAMMATAN, KASRATAN, 
FATHA, DAMMA, KASRA, SUKUN, SHADDA]) + u"]", flags=re.UNICODE)

or:

HARAKAT_pat = re.compile(ur"(?u)[" + u"".join([FATHATAN, DAMMATAN, 
KASRATAN, FATHA, DAMMA, KASRA, SUKUN, SHADDA]) + u"]")

I don't know whether that will make a difference in this case because I
don't know Tashaphyne or Arabic.
