It's unsurprising, certainly. It's not a bug in 2.4, though. -U is for
experimentation only, not for actual use. Python will change to only using
Unicode strings in 3.0, but not before then. Python 3.0 will add a bytes type to
replace non-text strings like those read from /dev/urandom in that piece of
code. os.urandom() and the random module will have to be modified to use it
instead of a string. Looking at the Python 3.0 branch, I see that this hasn't
quite happened, yet.

If I sent a user an empty database container - dB with no tables and I
needed them to import their tables into it and one of their tables was a
hidden table with the prefix Usys, is there any way in code I can get that
table imported without them having to go to options and show hidden tables
and then import it manually?

Hello
I am getting somewhat random UnicodeDecodeError messages in my program.
It is random in that I will be going through a pysqlite database of
records, manipulate
the results, and it will throw UnicodeDecodeError apparently without
regard
as to what data is being used.

Okay I'm getting really frustrated with Python's Unicode handling, I'm

Could someone explain to me what I'm doing wrong here, so I can hope to
throw light on the myriad of similar problems I'm having? Thanks :-)

Hello,
I'm working on an unicode-aware application. I like to use "print" to
debug programs, but in this case it was nightmare. The most popular
result of "print" was:
UnicodeDecodeError: 'ascii' codec can't decode byte 0xXX in position
0: ordinal not in range(128)
I spent two hours fixing it, and I hope it's done. The solution is one

This may seem very strange, but it is true.
If I delete a .pyc file, my program executes with a different state!
In a single directory I have

module1 imports random and MyClass from module2.
module2 does not import random.
module1 sets a seed like this::

Hi All,
I am relatively new to python unicode pains and I would like to have
some advice. I have this snippet of code:

argstr = list()
for arg in appcfg.options.split():
thefile = args
filemask = u"%file%"

if you can print out values of 'filemask', and 'thefile' variables, when it crashes, I can help.
thx. Edwin

I've found a painful bug when running an Access 2003 database under

Some combo boxes on some forms become transparent when they lose

which forms are affected. I've tried importing the forms into a new
