Python 3 Warnings

Make python code continue after exception up vote 4 down vote favorite 1 I'm trying to read all files from a folder that matches a certain criteria. My program crashes once I have an exception raised. I am trying to continue even if there's an exception but it still stops executing. This is what I get after a couple of seconds. error Here's my code import os path = 'Y:\\Files\\' listing = os.listdir(path) try: for infile in listing: if infile.startswith("ABC"): fo = open(infile,"r") for line in fo: if line.startswith("REVIEW"): print infile fo.close() except: print "error "+str(IOError) pass python share|improve this question asked Sep 25 '13 at 0:34 Ank 1,500133574 "I am trying to continue even if there's an exception"- never do this unless you have a clear plan for how your program should continue. Assuming that your code after the except: block relies on the file contents, continuing on after an IO error is a bad idea. Let the exception crash the program instead, so that you can actually notice and fix the underlying problem. –musical_coder Sep 25 '13 at 0:52 add a comment| 3 Answers 3 active oldest votes up vote 14 down vote accepted Put your try/except structure more in-wards. Otherwise when you get an error, it will break all the loops. Perhaps after the first for-loop, add the try/except. Then if an error is raised, it will continue with the next file. for infile in listing: try: if infile.startswith("ABC"): fo = open(infile,"r") for

Join them; it only takes a minute: Sign up python catch exception and continue try block up vote 13 down vote favorite 1 Can I return http://stackoverflow.com/questions/18994334/make-python-code-continue-after-exception to executing try-block after exception occurs? (The goal is to write less) For Example: try: do_smth1() except: pass try: do_smth2() except: pass vs try: do_smth1() do_smth2() except: ??? # magic word to proceed to do_smth2() if there was exception in do_smth1 python exception share|improve this question asked Oct 22 '13 at 16:08 kitty 1,1432717 You cannot return to a try block once interrupted, no. –Martijn Pieters♦ Oct 22 '13 at http://stackoverflow.com/questions/19522990/python-catch-exception-and-continue-try-block 16:11 I think no. Some structure have to segment flow, and specify next point to execute at (do_smth2 in this snippet) . –Jokester Oct 22 '13 at 16:11 3 possible duplicate of A Pythonic way for "resume next" on exceptions? –Martijn Pieters♦ Oct 22 '13 at 16:16 @MartijnPieters thats right, I googled too bad ;( –kitty Oct 22 '13 at 16:20 if you aren't even going to check to see if do_smth1 took an exception or not... then do_smth1 should eat the exception itself and not pass it up. but probably, you do care, and this isn't the right flow. –Corley Brigman Oct 22 '13 at 16:45 add a comment| 7 Answers 7 active oldest votes up vote 16 down vote accepted No, you cannot do that. That's just the way Python has its syntax. Once you exit a try-block because of an exception, there is no way back in. What about a for-loop though? funcs = do_smth1, do_smth2 for func in funcs: try: func() except Exception: pass # or you could use 'continue' Note however that it is considered a bad practice to have a bare except. You should catch for a specific exception instead. I captured for Exception because that's as good as I c
