It’s a common programming task to loop iteration while not receiving next item. For example:

for sLine in oFile :   if ... some logic ... :     sLine = oFile.next()     ... some more logic ...     # at this point i want to continue iteration but without     # getting next item from oFile. How can this be done in python?

  1. What you need is a simple, deterministic finite state machine. Something like this…

    state = 1 for sLine in oFile:    if state == 1:       if ... some logic ... :          state = 2    elif state == 2:       if ... some logic ... :          state = 1
