Well, if you feel like cheating, you could use the Tkinter mainloop:
import os
from Tkinter import Tk
root = None # invisible tk window
DELTA_T = 10000 # 10 seconds
def checkdir(path='.'):
print os.listdir(path) # do whatever check you wish
root.after(DELTA_T, checkdir)
if __name__ == '__main__':
root = Tk()
root.withdraw()
checkdir()
try:
root.mainloop()
except KeyboardInterrupt:
pass
The advantage is that you can every easily schedule recurring and
non-recurring events.
