I just happened to look at a compiled Python 2.6.4 .PYC file in
an editor and noticed that the full path and file name of the
compiled module showed up in my .PYC file at least 10 different
times. Is there a reason for full vs. relative path names and why
does the module name need to be duplicated

You have a function called "csv" that's defined after the import csv
statement is executed. That function has no attribute 'reader",

Quickly, I have a Mac Intel with Windows XP installed. Tried installing
Python 2.6.4 from the binary and also ActivePython 2.6.4.10. Both
installations acted the same. There seemed to be no problems during
installation (used default options), but when I try to run Python I get
an error message:

I should point out that leading-and-trailing-double-underscore names are
reserved for use by the language.
It's unlikely that Python will introduce a special method named
__orig_get__, and in truth the pr

This has to be a stupid question, but :)
I have some generators that do stuff, then start yielding results. On
occasion, I don't want them to yield anything ever-- they're only really
"generators" because I want to call them /as/ a generator as part of a
generalized system.
The only way I can fig

This is (pretty much) what the above code does.
>>> f = []
>>> n = 2
>>> f.append(lambda x: x**n)
>>> n = 3
>>> f.append(lambda x: x**n)
>>> n = 4
>>> f.append(lambda x: x**n)
>>> n = 5
>>> f.append(lambda x: x**
