You can probably achieve what you want just by structuring the program 
correctly. My guess you need to use nested loops, something like this:

while True:
  while True:
    if something_is_wrong():

This will do_some_work() until something_is_wrong(), then it will 
initialize_everything() and try again.

If the test for something_is_wrong() is buried deep in the code you can 
break the loop by raising an exception which you catch in the top-level
