Why does python break IEEE 754 for 1.0/0.0 and 0.0/0.0?

2005-07-14 Thread Grant Edwards
I've read over and over that Python leaves floating point issues up to the underlying platform. This seems to be largely true, but not always. My underlying platform (IA32 Linux) correctly handles 1.0/0.0 and 0.0/0.0 according to the IEEE 754 standard, but Python goes out of its way to do the w

Hi, I have another Tkinter-related question. At the beginning of my program, a tkinter window is created with six buttons. Each of these buttons is assigned a function that should be executed only when the button is pressed. However, it seems that these functions are all executed once w

2005-07-14 Thread Larry Bates
ODBC is a vanilla interface that puts a layer between the program and the database. In theory, this would allow you to write a program that supports ODBC compliant databases and it would work with any of them. In practice it always seems like this doesn't work as well as everyone had hoped (perfo

I concur with Larry. I find that by properly abstracting the database connection code in my own class, I can then use any DB-API-compliant Python module to connect to a variety of databases. I use for example cxOracle to connect to Oracle and kinterbasdb to connect to firebird. I haven't tried conn
