I am a total newbie surrounded by Python books and tutorials. Before I
became the one (this was not difficult :-)) I tried to learn a bit of C (I
am glad I did not). I found Python and this mailing are the best things for
what I dream to do.

This is my pet project. I would like to write a python program that allows
me to maintain  players' ranking for our bridge club. I run weekly
duplicate games and use a designated program to score these games. Among
other things it creates text files (see examples attached) with the game
results. I want to use the players' Pct (second column) and Names (last
column) to do my calculations.

The first things I want to know is:
-    how to get the data from the results file, i.e. how to create a
table/file with each player's name associated with the pair's Pct (what
type of file/string operation applies)?
-    how to use this individual player result to update the ranking
table/file? This would take:
     -    player's current ranking (first entry = 50.00),
     -    partner's current ranking,
     -    last game Pct for this pair, and maybe
     -    the average ranking of all players in the game.

I want to include the last 8 games in these calculations and produce a
current club ranking list for players that participated at least in 4 out
of the last 8 games.

I've gone through several tutorials, concentrating especially on file
operations/string manipulations but I do not know where to start and I
would appreciate any advice from you.

By the way, are there any duplicate bridge players on this mailing list
*grin*?
