Question

In file1.py:

      def test1():
        print "hi"

In file2.py:

      from file1 import test1

      def test2():
        print "hello"

      test1()
      test2()

Output:

      hi
      hello

Now in file 1 if i include test2 i get the following error:

    from file2 import test2

    def test1():
      print "hi"

   Traceback (most recent call last):
   File "file1.py", line 1, in ?
   from file2 import test2
   File "/root/pyt/file2.py", line 1, in ?
   from file1 import test1
   File "/root/pyt/file1.py", line 1, in ?
   from file2 import test2
  ImportError: cannot import name test2

Can some explain why and how to make it work?

Answer 1

The name doesn’t exist in the module by the time you try to access it.
