Thanks for your reply.  Now I'd like to discuss something about regular=20
expressions. :p

According to this link:
http://www.dragonkong.com/classic-chinese-mahjong-hands.html

=46ourfold Plenty means Four Kongs.  Is that true?

If yes, then according to the python regexp syntax page you provided,=20
\d means [0-9], and hence (.\d\d\d){0,1} means

"any char, plus three digits, the whole group repeats 0 or 1 time".  Is tha=
t=20
correct?

I don't understand how it is related to four kongs.

Also, what does "(.4\d\d)" mean?

*  *  *

Another question is about "Winding Snake".  Here is the code of predefined.=
py=20
in trunk:

         self.winnerRules.append(Rule('Winding Snake',
                 r'I^(([sbc])1\2[1]\2[1] \2[2]\2[2]=20
\2[3]\2[4]\2[5]\2[6]\2[7]\2[8] \2[9]\2[9]\2[9] [fy/])' \
                 r'|^(([sbc])1\4[1]\4[1] \4[2]\4[3]\4[4]=20
\4[5]\4[5]\4[6]\4[7]\4[8] \4[9]\4[9]\4[9] [fy/])' \
                 r'|^(([sbc])1\6[1]\6[1] \6[2]\6[3]\6[4]=20
\6[5]\6[6]\6[7]\6[8]\6[8] \6[9]\6[9]\6[9] [fy/])',
                 limits=3D1,
                 description=3Dm18n('All tiles of same color. Pung or Kong =
of 1=20
and 9, pair of 2, 5 or 8 and two '
                 'Chows of the remaining values')))

I don't understand what "1\2[1]\2[1] \2" mean.  According to the python reg=
exp=20
syntax page, "\number" means "Matches the contents of the group of the same=
=20
number. Groups are numbered starting from 1. For example, (.+) \1 matches '=
the=20
the' or '55 55', but not 'the end' (note the space after the group). "  But=
 I=20
can't explain the above regexp.  \4, \6 means to match the contents of the=
=20
group four and six more times?

Also, the description of it, "All tiles of same color.  Pung or Kong of 1 a=
nd=20
9, pare of 2,5,8 and two chows of the remaining values".  I can't match it=
=20
with the regexp, also I can't understand the tiles:

111225588999  then two more chows?

In the page I provided there is a "The Wriggling Snake" but it is totally=20
different then the "Winding Snake" here.  Could you please explain it more?


Thanks,
