Python scheduler

[Rita]

Hello,


Here is what I am trying to do. (Currently, I am doing this in cron but i
need much more granularity). I am trying to run program every 20 secs and
loop forever. I have several of these types of processes, some should run
every 5 mins, 10 secs, 20 secs, 1 min and so forth. I was wondering what is
the best way to do this?


Also, would Greenlet do something I am asking for?

Erlang, which is geared for such stuff, has its own internal cron
https://github.com/erlware/erlcron with 2 sec granularity.
Not an ideal solution I guess. Anyway since you are using cron (ie
not within the python ecosystem) I am pointing this out. Then you
could use the erlang equivalent of python's os.system. In erlang its
os:cmd http://www.erlang.org/doc/man/os.html
