'local' var in module

[Andreas Lobinger]

Aloha,

i'm i little bit confused by the following behaviour...

lobingera at sibyl: cat flip.py
import random

paras = { 'flength' : 22,
           'cset' : 'abcdefghijkl' }
rstate = 1

def f():
    random.seed(rstate)
    s = list()

    for i in range(paras['flength']):
       s.append(random.choice(paras['cset']))

    return "".join(s)

def g():
    random.seed(rstate)
    s = list()

    for i in range(paras['flength']):
       s.append(random.choice(paras['cset']))

    rstate = random.getseed()
    return "".join(s)

I try to save the state of the random module locally in flip.
I also have other parameters (paras) in the module.

'akdkdgkaiflieafceagele'
 >>> flip.g()
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
   File "flip.py", line 17, in g
     random.seed(rstate)
UnboundLocalError: local variable 'rstate' referenced before assignment
 >>> flip.f()

Somehow 'rstate' is readable in f, but not in g, but paras is?

Wishing a happy day
