Declaring variables from a list

[Cactus]

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,
Cacti

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'

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.

locals = locals()
locals["a"] = 5
a 5
locals["a"] = "changed"
a 'changed'

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

Thanks,

I'll look in to that. Seems like that will work....
