Python Using methods from other modules -

i have 2 modules called dfs , graph. in graph module, have class graph , method called readgraph. in dfs module, have method calls on readgraph following error message when type: dfs.processgraph(testcase.txt,verbose=true)

error message: nameerror: name 'testcase' not defined

could explain how fix this?

thanks.

from dfs.py module:

import sys  graph import *  class dfs( object ):     def processgraph(file_name, verbose):       g=readgraph(file_name) 

from graph.py module:

class graph( object ):     def readgraph( file_name ): 

remove class declaration graph.py. when import file top level objects. in case it's graph class itself, not methods.

also need pass string 'testcase.txt' not testcase.txt.
