I am learning to write .py program and come across something that contains “Graph() function”. When I ran the program, it gave me the following error:
NameError: name ‘Graph’ is not defined
How can I resolve this issue? Your feedback is much appreciated!
Hello,
You would need to paste the relevant portion of your code here for someone to help debug this problem. Can you please paste your code up to the line that produces the error message?
Thank you.
The issue was overlooked and resolved. The ticket can be closed. Thanks.
It’s always helpful to include the solution in your reply, in case another user experiences a similar problem. I’m assuming you needed to import a particular module? Something like:
from import Graph
I often find that code examples taken from online are missing import statements as the online source likely has some automatic imports defined in their IDE.
Graph module was actually defined as follows:
class Graph:
class __Edge:
def init(self, capacity=1, **args):
self.capacity = capacity
def init(self, n=0):
self.__N = n
self.edges = [{} for _ in range(n)]
