Python 101 (part 8): An Exceptionally Clever Snake
In this concluding article of the Python 101 series, find out howto use Python's exception-handling routines to trap and resolve programerrors, learn to generate and use custom error messages, and get acquainteda bunch of useful (and free!) Python resources online.
If you've been following along since the beginning, I think you'll agreewith me that it's certainly been an interesting eight weeks.
Together, we've visited all the standard attractions - we've thumbedthrough the rulebook for strings, numbers, lists, dictionaries and thoseoddly-named tuples; mucked around with system files and directories;packaged code into functions and functions into modules; and dissected thePython interpreter and some of Python's innumerable built-in functions -and indulged in some decidedly non-standard activities - learning the namesof exotic Italian dishes; stomping on all kinds of creepy-crawlies;attempting to con unwitting customers into purchasing air in a bottle; andhooking up with old flames, new superheroes and the complete cast of "StarWars".
In this concluding article, I'm going to be demonstrating Python'serror-handling routines, and showing you how to wrap your code in them toavoid violent - and potentially embarrassing - flame-outs. I'll beexplaining the different types of errors you might encounter and the Pythonconstructs available to manage them, with examples that demonstrate justhow powerful this capability really is.
