exec behaviour; Functions as instance members.

[Michel NIZETTE]

Hello,

Two questions from a beginner :

1) Inside a function definition why doesn't

exec "global i"
exec "i = 1"

set the global variable i to 1, although

exec "global i\ni = 1"

does ?

2) To define a function as a member of a class instance, is there a
shorter way than introducing a temporary function name as in the
following ?

def Temp():
    # Code...
ClassInst.Func = Temp
del Temp

Thanks !
