Hey all,
Sorry for the bother, thanks for the help.
I'm trying to write a password guessing program to keep track of
how many times the user has entered the password wrong.
If it is more than 3 times, print ``That must have been

Hey Gary

the variable password has to be here because you are referiencing before the
assignment inside the while sentence. You can also set it to password= and
still will work because you have to tell (in this

Hi Brian
Thanks for correcting me about the variable and reserved word differences (just
for the record the problem is that my english is not so good, you see I'm from
Bolivia so pardon my francôis :P)
Hi Alberto,
I wouldn't have known

Hello Brian
I think the source of your problem is that the second instance of
Wall_clock doesn't get deleted in the interval doctest. This is
critical, because the is_instanced attribute is reset by __del__.
def interval(self, interval_name
Lee Harr said unto the world upon 2005-04-10 10:21:
I have apparent interference between doctests embedded in the
docstrings of different methods, and this interference also appears to
be influenced by seemingly irrelevant things such as whether the
module has a (non-doctest-containing) docstring
) and the call of
Wall_clock.__del__() helps explain a good deal. Thanks for pointing
that out!

Hi all,
I must apologize for the length of the post. I have explained my
problem as tersely as able, and have done my level-best to produce the
minimum code snippet illustrative of my difficulties. But, as (I hope)
will become clear, any substantial attempts to further cull it made
the problem

Hi all.
I would like some crituqe on this code.
It is three separate files (all put on one web page)
Each one is labeled in the comment that begins each section of code.
It is a little longer when I put it all on one page, so I have it up

This is not a great way to start on this list, but I am having trouble

an answer to elsewhere.

I had thought lookup was by hash value, and thus expected the access
to some_dict to cause troubles. Yet it worked. Is it that lookup is by
hash value, and then equality if need be so
Danny Yoo said unto the world upon 2005-03-29 03:37:
*Almost* all ints are fixed points for the hashing function in the
sense that hash(some_int) == some_int. Almost all as:
hash(-1)
-2
Any idea why -1 is the sole exception?

What?!?!
OK, floats don't necessarily have the exact values you expect

Snip much useful discussion
I know I'm rushing this, so please feel free to ask more questions about
this.
Hi Danny, Orri, and all,
I'm really glad Orri raised the hashing issues he did, and appreciate
your informative posts, Danny. :-)

Is there a special startup script the command-line python IDE and/or
IDLE use? As per Liam's response to my previous post, I would like to
use os.walk() to automatically set my sys.path() variable...
