I think it is because you are always printing a value. So, you are not over-writing 'a' ni the instance of the 4th line, so when you print the variable, you are getting the last stored value of 'a'.
Perhaps as the first line ater your else, do a
Code:
a=""

to blank out the last 'a' value?

NAME
netris-sample-robot - sample robot for netris SYNOPSIS
netris-sample-robot [-l] DESCRIPTION
The netris-sample-robot is a sample implementation of the robot protocol. It plays quite well but isn't too hard to beat. The robot should be started from netris with the option -r to connect or wait for another player to join. You can also let two robots play against each other in that way, if you like. OPTIONS
-l Writes some log information into the file log in the current working directory. If it can't it bails out. EXAMPLES
To start the netris-sample-robot waiting for another connection with logfile use the following line: netris -w -r 'netris-sample-robot -l' You then just have to start netris somewhere else which connects to that robot. SEE ALSO
netris(6) BUGS
One known bug of the netris-sample-robot is that it hangs quite often. This was already filed as a bugreport against the package so please refrain from doing so again. If you have an idea why this happens or know a solution how to fix it feel free to mail us. AUTHORS
