I think you may be looking for something that is not needed in Python or that you can easily do
another way.
If you are running a script from the command line, e.g.

then myscript.py will have a completely fresh runtime environment every time
you call it.
If you are running
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
Hi,
After searching a while for a solution on the web and the archive of
this newgroups, I haven't found any answer to my questions... So here
are they...
Here is a command line session of Python on a Windows XP computer :

I'm still not sure why there is a problem. How are you running the scripts from the interactive
session? If you are importing the script, its variables will be in its own namespace. If you are
creating variables interactively yourself, your best bet is probably to just restart the
interpreter. (

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!):

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)?

than passing around an instance of the main Burn class.
