Alan was saying that there is no other obvious way for Python to do
it.
What I am still not clear on it is why Alan's claim is true. (Not
doubting it is, but would like to get why it is.)
Doubt away, my knowledge of Python internals is largely intuitive,

I am curious about Bob's Whenever you find yourself writing an if
statement ask whether this would be better handled by subclasses.
Could you explain a bit more?
One of the basic purposes of OOP is to eliminate if/switch statements
that are conditional on the type of the object being handled.
...So, trying to get this straight - if I were going to use SQLite,
what would I actually download from http://www.sqlite.org/sqlite.html
?
Also, would Gadfly be easier, being native Python?

The way you want to work with closures the Python way is not to do it
but use a class to hold the state. That's sometimes sad but true.
example if I have:

SQLite itself does not use / interface with Python. So you would download the appropriate version of

I'm pretty sure you have to explicitly pass self.

You can use the string split() method to get a list of the
components. Then
OK, so it looks like you're not matching.
Remember match only matches at the start of a line, so try re.search instead.

The os module is the answer. Use chdir() to make the target executable's

the actual command.
