for search in range(200):
     for t in range(MAXRETRY):
     	try:
         	result=requestfromserver(...)
                 break
     	except IOError,e: # or whaterver error you get
             time.sleep(10)
             # log something ...
     else: # if above runs w/o break
         raise XYZError...() # define appropriate for your app

     # here you can work with result
