Yeah, it has the same structure internally, but I'm somewhat
surprised that the DB connection object doesn't have an
__iter__() that does something like this automatically under the

The use of eval is dangerous if you are not *completely* sure what is
being passed in. Try using pickle instead:

Those changes can be automated, given an adequate editor. "Oursql" is a
far better product than the primitive MySQLdb wrapper. It is worth the

PHP is a language that I wish would die off quickly and
gracefully. I feel like the good things of PHP have already
been subsumed into the ecosystems of stronger programming
languages (including Python).
The one killer feature PHP has to offer over other languages:

All of them should do so. They're just string being passed to CreateFile,
