I'm a Python newbie, but I've just spent a day working out how to get MySQLdb working properly, and the universe according to google includes numerous references to what a PITA it is, and an inordinate number of guides that seem to be outdated. Given that this site is intended to address these sorts of problems, and I know that I'm goin...

We have class User( db.Model ) : email = db.StringProperty() name = db.StringProperty() password = db.StringProperty() # more fields.. Because the user account is accessed so often, we keep a copy in session using gaeutili...

For instance to install Mechanize, I'm just supposed to put the Mechanize folder in C:\Python24\Lib\site-packages according to INSTALL.txt, but runnning the tests does not work. Can s...

One of them basically just loads up a Python module and executes a specific function, passing it keyword arguments. In PyObjC, this was extremely. However, I'm having difficulty figuring out how to do the same thing using the P...

Both are using the same code, and the same font file (VeraMoBd.ttf), the same version of PIL (1.1.6), and the same Python version (2.6). I g...
I'm trying to convert a 2.5 program to 3. Is there a way in python 3 to change a byte string, such as b'\x01\x02' to a python 2.5 style string, such as '\x01\x02', so that string and byte-by-byte comparisons work similarly to 2.5? I'm reading the string from a binary file. I have a 2.5 program that reads bytes from a file, then compare...
