使用python从.csv文件读取边缘到igraph

Question

Let's say I have a .csv file containing the following:

Apple    Banana
Apple    Coconut
Banana   Coconut
Coconut  Apple

And these should mean directed edges between two nodes, like: Apple->Banana, Apple->Coconut, etc.

What is the proper method to use this kind of input in igraph?

Answer 1

This is what the Read_Ncol(f, names=True, weights="if_present", directed=True) function exactly does.

>>> from igraph import *
>>> g = Graph.Read_Ncol("stuff.csv", directed=True)
