An example in the book I didn't understood well
two modules files recursively import/from each other
in recur1.py,we have:
x=1
import recur2
y=1
in recur2.py, we have
from recur1 import x
from recur1 import y
If we run interactively at python command line,
>>> import recur1
it has errors like this:
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "recur1.py", line 2, in ?
import recur2
File "recur2.py", line 2, in ?
from recur1 import y
ImportError: cannot import name y
I understood this because recur1 is not finished when recur2 is trying
to import y.
However, if you run interactive for recur2.py interactively, it is
fine.
when you run as script from command line, recur1.py is fine. but when
you
python recur2.py at commmand line, it has errors like this:
Traceback (most recent call last):
File "recur2.py", line 1, in ?
from recur1 import x
File "recur1.py", line 2, in ?
import recur2
File "recur2.py", line 2, in ?
from recur1 import y
ImportError: cannot import name y
What's really the problem here?
Thanks
