You’ll have to make this separate try blocks: try: code a except ExplicitException: pass try: code b except ExplicitException: try: code c except ExplicitException: try: code d except ExplicitException: pass This assumes you want to run code c only if code b failed. If you need to run code c regardless, you need to put … Read more
You have to define which type of exception you want to catch. So write except Exception, e: instead of except, e: for a general exception (that will be logged anyway). Other possibility is to write your whole try/except code this way: try: with open(filepath,’rb’) as f: con.storbinary(‘STOR ‘+ filepath, f) logger.info(‘File successfully uploaded to ‘+ … Read more
If you are storing reference types in your list, you have to make sure there is a way to compare the objects for equality. Otherwise they will be checked by comparing if they refer to same address. You can implement IEqualityComparer<T> and send it as a parameter to Except() function. Here’s a blog post you … Read more
Change except InvalidUserPass, e: to except InvalidUserPass as e: See this for more info.
If you want a list of a single property you’d like to intersect then all the other pretty LINQ solutions work just fine. BUT! If you’d like to intersect on a whole class though and as a result have a List<ThisClass> instead of List<string> you’ll have to write your own equality comparer. foo.Intersect(bar, new YourEqualityComparer()); … Read more
You could use get twice: example_dict.get(‘key1’, {}).get(‘key2’) This will return None if either key1 or key2 does not exist. Note that this could still raise an AttributeError if example_dict[‘key1’] exists but is not a dict (or a dict-like object with a get method). The try..except code you posted would raise a TypeError instead if example_dict[‘key1’] … Read more
Bare except will catch exceptions you almost certainly don’t want to catch, including KeyboardInterrupt (the user hitting Ctrl+C) and Python-raised errors like SystemExit If you don’t have a specific exception you’re expecting, at least except Exception, which is the base type for all “Regular” exceptions. That being said: you use except blocks to recover from … Read more
