[Tutor] static variables - lock/semaphore

[anil maran]

hi
i have a program that is run on a website, and as it
is run from a website, it can be called more than once
and hence could end up corrupting db/data
is there a way to use some sort of semaphore or lock
so that it is not accessed simultaneously
the problem is it can be done with static variables in
C but how is it done in python
thanks a lot
