Hello again everyone ,
var2[:]=[] has solved my problem, and I don't understand why it is
programming by side effect.
I don't think it's bad, look at this, it's what I've done :
def Clear(lvar)
lvar[:]=[]
def main (starting class)
var1=[]
var1.append('a')
Clear(var1)
var1 can only be modified by Clean(), so, if I need to debug var1, I
quickly know that I must look in Clean()
For me programming by side effect is that :
def Clear(lvar)
var1=[]
def main (starting class)
global var1=[]
var2=[]
var1.append('a')
Something(var2)
I am wrong?
Dominique.
