Circular import itself isn't a problem--Python will deal with that.
Problems arise according to the order in which classes, etc. are loaded
from each module and where the required classes are used. As the
previous poster mentioned, you can get around this by moving one of the
import statements inside a function. You can also move one of the
statements to the bottom of the file. Consider two modules:
*bar.py*
from foo import Bar
Class MyBar:
foo_cls = Foo
*and foo.py*
from bar import MyBar
class Foo:
def foo(self):
return MyBar()
This will cause a problem because foo imports from bar, but bar will
need foo.Foo because it's referenced at the top level of the MyBar
definition. However, you can move the import in foo.py to the bottom, so
that bar isn't imported until Foo has been defined.
