able to run just fine. The problem is if you leave the except: block empty or with a #do nothing, it gives you a syntax error. I can't use continue because its not in a loop.

According > to this > link, 'continue' is allowed within an except or finally: Thats true but only if the try block is inside a loop. Consider: error = True def f(): if error: raise ValueError else: print 'In f()' def g(): print 'In g()' while True: try: f() g() except ValueError: error = False continue continue will cause the *next* iteration of the loop to start. Thus the first time round the error is raised in f() and the code jumps to the except clause and from there back to the top of the loop, effectively missing g() out, then next time through no error is raised so both f() and g() are called. If you really want to ignore the error and move to the next line you have to do a try:except on every line (or function call) try: f() except: pass try: g() except: pass Or put the functions in a list if their parameter lists are null or identical: funcs = [f,g] for func in funcs: try: func() except: continue But all of that's bad practice since who knows what nasties you might be allowing through. Its usually possible to structure code to avoid such horrors!
