Hi,
If I got a list is it possible to declare a variable from the items in that list?
Code Sample:
Blob = ['Var1', 'Var2', 'vAR3']
i = 5
for listitems in Blob:
i += 1
listitems = i
print Var1
6
print Var2
7
print vAR3
8
Something like that? This doesn't work (obviously) but is there a way to do this?
TIA,

if you want a dictionary, use a dictionary (see the tutorial for details).

Python has a builtin function called locals which returns the local
context as a dictionary locals = locals() locals["a"] = 5 a
5 locals["a"] = "changed" a
'changed'

From Python lib reference:
"""
locals()
...
Warning: The contents of this dictionary should not be
modified; changes may not affect the values of local variables used
by the interpreter.
"""
What I gave was a bad solution. Something that works right now, but
probably shouldn't be done.

You can use the built-in statement exec
( http://www.python.org/doc/2.4.1/ref/exec.html) :
# Blob = ['Var1', 'Var2', 'vAR3']
# i = 5
# for listitems in Blob:
# i += 1
# exec('%s = i' %listitems)
#
# print Var1, Var2, vAR3

Hi,
I have a question about declaring variables for writing data to a file for
random access.
I have two string variables declared in a module (user-defined types).
The point is that for one of them i can't define (hard coded) a fixed
length because the application is reading data
from another file (In that file they have the same lenght).
Is it possible to use the lenght i obtain from reading that other file to
declare my variable or...

I am wondering if anyone has any insights on the performance benefit (or
detriment) of declaring local variables instead of referencing members.
Is allocating memory for a new variable more efficient than repeatedly
referencing the member in a loop?
Maybe using a string isn't the best example, but hopefully you get the
idea!

Hi guys.
I have a question about declaring variables. I do a lot of re-querying
of controls in my database and I use the Set statement with a variable
set to the name of the control to tell the program which control to
requery. This makes it easy to requery controls on a different form.
However, up until today, I was dimming a new local variable for each
control I wanted to deal with ( E.G. Dim cbxctl as control) and then
setting that...

I have a problem declaring variables. I need to create an object oRpte

I've always wonder if there is diference when declaring and
initializing a varible inside/outside a loop.
What's a better practice?
Declaring and initializing variables inside a loop routine, like this:
for(var i=0; i<list; i++)
{
var name = list;

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
