No more then 1 Instance of Application..

[Math]

Hello,

Pardon my English...
Does anybody know what I have to do to run only 1 instance of my Python
Application?
How do I check if I'm running more instances of a Application?
Thank you all

Yes.

On Unix, one creates a lock file. Typically
/var/run/<appname>.pid if you want a single system-wide
instance.
