[Solved] How can i make self updating list in python?

Keep the variable a outside loop.

def deviser(n):
        a=[];
        i=1;
        while( i<= n):
                x=n%i;
                if( x == 0 ):
                        p = a.insert(0, i);
                        print i;
                i = i+1;
        return a;

>>> deviser(18)
1
2
3
6
9
18
[18, 9, 6, 3, 2, 1]
