Re: Declaring variables from a list

[Pierre Quentel]

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

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

Thanks,

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

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

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()

What I gave was a bad solution. Something that works right now, but
probably shouldn't be done.
