how dump a program which is running in memory

[ruqiang826]

hi
I have written a service running backgroud to do something in linux.
unfortunately，I deleted the source code by mistake, and I can still
see the process running background using "ps aux" :

username   13820  0.0  0.0 60368 2964 ?        S    Aug20   0:33
python ./UpdateJobStatus.py


I wonder if there is some way to dump the programme
"UpdateJobStatus.py" and get the source code back?


Thanks a lot.
