Module object is not callable when using defaultdict package not working in PyCharm [closed]

I am trying to implement DFS Graph in python and I am newbie I am Python programming. I import defaultdict package in this code.I face this error and I was not figure out this error:

Traceback (most recent call last): File “/Users/abdullahsheikh/PycharmProjects/Implement_dfs/main.py”, line 26, in DFS_graph=DFS_() File “/Users/abdullahsheikh/PycharmProjects/Implement_dfs/main.py”, line 6, in init self.graphlist = defaultdict(self) TypeError: ‘module’ object is not callable

code sample is :

import defaultdict

class DFS_:
  def __init__ (self):

      self.graphlist = defaultdict(self)

  def AddEdge(self,n,v):
      self.graphlist[n].append(v)

  def DFSfun(self,v,visited):
      visited[v] = True
      print(v,end= ' ')
      for i in self.graphlist[v]:
          if visited[i]==False:
              self.DFSfun(i,visited)

  def _dfs(self,v):
      visited = [False] * (max(self.graphlist)+1)
      self.DFSfun(v,visited)





DFS_graph=DFS_()

l = int(input("Enter total number of Edges"))
for i in range(l):
  firstpoint = int(input("Enter first point"))
  secondpoint = int(input("Enter Second point"))
  DFS_graph.AddEdge(firstpoint,secondpoint)

startpoint = int(input("Enter starting point: "))
DFS_graph._dfs(startpoint)

Answer

There are multiple issues here.

1. from collections import defaultdict instead of import defaultdict

2. self.graphlist = defaultdict() instead of self.graphlist = defaultdict(self)

3. Not sure what the methods are supposed to do. AddEdge should probably be something like:

    def AddEdge(self, edge, first_point, second_point):
        self.graphlist.update({edge: [first_point, second_point]})
   

   The other methods need a clean up, too.
