i am using pyramid in views.py
from pyramid.response import Response
from pyramid.view import view_config
import os
import uuid
import shutil
import hashlib
from .service.fun import *
def forservo():
return "HAppy HERE"
@view_config(route_name='home',request_method='GET')
def home(request):
return Response('html')
in fun.py
from ..views import *
print forservo()
it throws error saying name 'forservo' is not defined
folder structure is
myapp
myapp
service
__init__.py
fun.py
__init__.py
views.py
You have a cyclic import - fun.py imports from views.py and views.py imports from fun.py.
In this situation, things happen roughly like this:
Python opens views.py and executes it up to the line from .service.fun import *
It then has to stop executing views.py and opens fun.py.
The very first line of fun.py tells it to stop and import views.py
The import statement returns the partially-executed module which does not yet have forservo function defined.
Cyclic imports can be resolved by moving the common bits of code needed both by fun.py and views.py into a separate module. A less elegant solution is to move some imports below the functions which are causing the cyclic import error or make them local inside a function which needs the import.
