No, you can't. ASCII strings only have characters in the range 0..127.
You could create Latin-1 (or any number of the 8-bit encodings out
there) strings with characters 0..255, yes, but not ASCII.

Hi I am a newbie for Python
Here is a question, say I have a list L,
function foo is:
def foo(L):
if L[0] 0: return True
if later I want another function goo which returns True when L[0]
and L[1] are both 0, i.e.,
def goo(L):
if L[0] 0 and L[1]
The md5 module is used in build xulrunner and Firefox from source. When I do

I ran a comparison that timed 1e6 file seeks.
The tests were run with Python 2.6.4 and Microsoft Visual C 6.0 on
Windows XP with an Intel 3GHz single processor with hyperthreading.
Results:
C: 0.812 seconds
Python: 1.458 seconds.
difference = 0.646 seconds.

I'm sure I would, but unfortunately I can't control the

This is a pretty tight loop:
for i in xrange(100):
f1.seek(0)
But there is still a lot going on, some of which you can lift out of
the loop. The easiest I can think of is the lookup of the 'seek'
attribute on the f1 object. Try this:
f1_seek = f1.seek
for i in xrange(100):

has anyone managed to integrate pexpect and logging?
I.e., I'd like to be able to pick up the dialog,

I know about the pexpect logfile, and I can log things
to stdout or stderr, but I really need to log using the
