Question

Is the below declaration wrong? It doesnt give any syntax error though but some times i see that b and a value append operations do not work in case of a list.

a=b=c=[]
 or 
a=b=c={}

a=b=c=1 //works

Answer 1

Have you tried it?

It depends what you mean by “wrong”. It’s not a syntax error, but it does mean that a, b and c refer to the same list. So if you subsequently append something to a, you’ll see it in b and c as well.
