A way to do this on DOS/Windows console would be:
import sys
for r in range(0,2**16):
line = "Count : %d" % r
sys.stdout.write(line)
sys.stdout.flush()
# do something that consumes time
backup = "\b" * len(line) # The backspace character; this will
prevent c

You can also patch the library to always return lists instead of generators.

You don't need to use __dict__ to set function attributes. Just do:
foo.color = 'blue'

The efficiently argument is specious. [This is a python list not a C

The real issue is that complex regexes are hard to get right -- even
if one is experienced.
This is analogous to the fact that knotty programs can be hard to get

One thing that comes to mind is importing. py2exe packs libraries in a zip file
so importing might be a bit slower. But this should slow only at the beginning
until everything is loaded to memory.
The other usual suspect is the anti virus :)

That would be an easy impression to get from this long rambling thread.
The argument that Python's ‘float’ type is not meant to be anything
*but* an IEEE 754 floating point type has been made several times.
