creating list n many times
How to define n many empty lists where n is the number of vertices of the given arbitrary graph.
Thanks in advance.
If n
is your number of vertices, you can for instance create a list of n
empty lists as follows:
sage: L = [[] for _ in range(n)]
And then you can access the (empty) list number i
(for i
from 0
to n-1
) using:
sage: L[i]
[]
sage: L[i].append(0)
sage: L[i]
[0]
