- static PyDiGraph.read_edge_list(path, /, comment=None, deliminator=None, labels=False)#
Read an edge list file and create a new PyDiGraph object from the contents
The expected format for the edge list file is a line seperated list of deliminated node ids. If there are more than 3 elements on a line the 3rd on will be treated as a string weight for the edge
path (str) – The path of the file to open
comment (str) – Optional character to use as a comment by default there are no comment characters
deliminator (str) – Optional character to use as a deliminator by default any whitespace will be used
labels (bool) – If set to
Truethe first two separated fields will be treated as string labels uniquely identifying a node instead of node indices.
