I'm having a problem where two modules depend on each other. I am using simple import statements, but it would create an endless loop as the two files try to import each other. Obviously python prevents this, but it only gets to a certain point in each file. This is rather hard to explain by text, so I'll try an explain by example.
You start off by parsing a.py
a.py
print "a"
import b
def d():
print "d"
b.py
print "b"
import a
def c():
print "c"
d();
c()
This will fail, because d has not yet been defined. The problem is, that code in b.py depends on code in a.py, and vice versa. Here is the output and eventual stacktrace.
a
b
a
c
Traceback (most recent call last):
