Method in Methods and Variables

[Thomas Guettler]

Hi!

The following python code behaves strange:

import re
def test(my_int, my_list):
     content='"a" "b" "c"'
     def sub(matchObject):
         my_string=matchObject.group(1)
         print my_int
         my_int+=1 # (*) If I uncomment this line it works
         print my_list
         return "-%s:%s-" % (my_string, my_int)
     content=re.sub(r'"(.*?)"',
                    sub, content)
     print content
test(12, [14])

-->
Traceback (most recent call last):
   File "sub-test.py", line 13, in ?
     test(12, [14])
   File "sub-test.py", line 11, in test
     sub, content)
   File "/usr/lib/python2.2/sre.py", line 143, in sub
     return _compile(pattern, 0).sub(repl, string, count)
   File "sub-test.py", line 6, in sub
     print my_int
UnboundLocalError: local variable 'my_int' referenced before assignment

If I uncomment the line (*) it works:
===> python sub-test.py
12
[14]
12
[14]
12
[14]
-a:12- -b:12- -c:12-

It is strange, that I can read my_int but I can't set it. I think
putting the integer into a list should work.
