I inserted x1,x2 into A to force a wider scope and it works.
#!/usr/bin/env python
def A():
print "begin A:"
A.x1=123;
A.x2=456;
def B():
print "begin B:",A.x1,A.x2
A.x2 = A.x2 + 210; # problem gone.
print "end B:",A.x1,A.x2
print "pre B:",A.x1,A.x2
B()
print "end A:",A.x1,A.x2
A()
$ ./z1z2.py
begin A:
pre B: 123 456
begin B: 123 456
end B: 123 666
end A: 123 666
$ python -V
Python 2.5b3
I checked: This method even handles recursion giving a new instance of
A.x2 each call.
Is this the official way to scope/inherit scopes in sub procs?
ThanX
