A bit of historic perspective. John Ousterhout invented TCl/Tk
to provide a control language for his electrical engineering
projects. Thus its focus is on GUIs to
Dear Kent,
Consider I'm working with an interactive session during which I have already
run some scripts. Those scripts have produced several variables, say, e.g.,
a and b. Now I execute myscript which also creates variables named a and b,
but with a possibly different type or content. To be sure

wondering if there is a better way to implement readline than what I
have below? It just doesn't seem like a very good way to do this.

def __init__(self,s):
self.macro=s
Best: use the StringIO or cStringIO module instead, this is exactly what it is for. If you really
need len() you could maybe subclass StringIO to do what you want.
Next best: Use an iterator. Something like this (Warning! not tested!):
class _macroString(object):
def __init__(self,s):
You could use trackback.extract_stack() to get the current stack trace. If you inspect this from
within the imported module you could probably figure out who is importing you.
Do you really want the module where the import was done (the place where the import statement is)?
Or are you trying to
Ok I will investigate this. Thank you that is probably what I
needed.

helpful to simulate adding keywords so that all these bloggers

Thank you KentBot. That was what I wanted.

Of course it would be nice if they added one now!!!

A few thoughts:
- you might want to make a configuration object that you can pass around, this is probably better
than passing around an instance of the main Burn class.
- typical Python style is *not* to define setter and getter functions. If you need to mediate
attribute access you can do it

Hi Danny:
Thank you for your suggestion. I tried creating a
dictionary of 'what' list and searched keys with
has_key method and it is pretty fast.
Thanks again. following is the piece of code.

for i in range(len(what)):
ele = split(what[i],'\t')

A couple of minutes of googling for 'python odbc' finds the ODBC driver that comes with win32all. It
