Re: issue
What kind of database do you need? Relational Databases? The three major databases you can work with python are SQLite, MySQL and PostgreSQL (favorite of mine.) SQLite already comes with python. Try: >>> import sqlite3 SQLite is... Lite. All the informations are stored in a single file. MySQL and PostgreSQL are more complete databases that run as servers on the machine, and you can use python bindings for both. (psycopg2 for postgres, and i forgot what binds mysql to python at the moment.) I guess you should google for psycopg2, read a little bit about the SQL syntax (though you may not need to use them directly, it`s good to understand what happens behind the bindings.) The PostgreSQL docs are quite good. Sorry for not providing any links. They should be easy to find if you google for them. 2009/1/19 amin > Hi dears. > I started programing with python and want to use a suitable > database.But I Know nothing about them.please introduse one to me. > thanks. > -- > http://mail.python.org/mailman/listinfo/python-list > -- "I May Be the Walrus." -- http://mail.python.org/mailman/listinfo/python-list

By his question i supposed that opening less files was not an 'ok' solution. But of course you can do that, and it is prefered if it won't interfere negatively in your program. -- "I May Be the Walrus." -- http://mail.python.org/mailman/listinfo/python-list

Re: New to python, open source Mac OS X IDE?
I would recommend Netbeans with Python plugin, Eric4 and Komodo Edit, with descending order of preference 2009/1/27 joseph.a.mar...@gmail.com > Greetings!

You shouldn't even think about hard tabs, and you should default all your editors to soft tabs. -- "I May Be the Walrus." -- http://mail.python.org/mailman/listinfo/python-list
