Personally I try to get the menu function to return the value selected
that way the meniu options and the code to check it is all wrapped
up in the same place.
But that is only a side issue...

Hi Mark,
Out of curios
One of the worst I think was doing loads of real spazzy stuff trying to
split whole files in to lists of letters and use string methods to find the
first uppercase one.
The re tutorial has sorted it out for me. I figured this was the way to go,
I just couldn't work out how to get the index valu

An alternative to pass is
raise NotImplementedError
This has the advantage/disadvantage of providing a meaningful exception
when you start testing and forget to provide some processing logic for a
stub function. pass will simply return None when used for a function
body. I nearly always

Hi William,
Ah! This happens to me too; one common idiom to avoid definition-order
issues like this
Hi,
I have to write a function that will return the index of a line like this:
gvcdgvcgdvagTVTVTVTVTVTHUXHYGSXUHXSU
where it first becomes capital letters. I've had about a hundred different
ideas of the best way to do this, but always seem to hit a fatal flaw. Any
thoughts?
Thanks,
Chris

I'd avoid using input. Use raw_input instead.

Hi John,
you can use 'pass' . This works the same as with exceptions, eg
try:
open('somefile')
except IOError:
pass
so we can have
class doNothing:
def __init__(self):
pass
def boring(self, other):
pass
Hope that helps :)

This is a problem if you are used to Perl, where the whole script is

Is there a way to create an empty function definition with no lines of code
in it? In my coding style I will often do this ( in other languages ) for
RAD just to remind myself that I will need to implement the function later.
