Re: Unsetting variables in Python

Hi all,
    Why do you need to "unset" a variable? In most other
languages that I have programmed in, if you need to "unset"
a variable then you usually give it a null value, ie stringv
= "". If it is a memory issue and a variable is of a set
length then you would free the memory using the appropriate
command. Are you trying to free up memory here? If not, why
bother killing the variable at all? If memory is not an
issue, then a dead variable won't make any difference
anyhow. If the program doesn't refer to the variable again
then it just takes up space. Sorry if this isn't much help,
but I am interested why you need to do this.
    Cheers!
        Andrew.
