[igraph] Weight & bool variable

[Ragia Ibrahim]

Hi,
kindly please :
I had a graph, i can assign weight for each edge, but can i assign other properties such as bool variable or other second weight.

Also how can i write "  each v belongs to set of V's " where V is nodes.
or should i write it in for statement :   for i in 1: lenght of v do
replying is highly appreciated
