I would scan all the attributes of mypythonlib. The dir function should print them all out and see what attributes are there and if they make sense.
from libpython-clj.
I'm a bit confused on how to scan all the attributes. I used this functions in clojure to print the module dictionary:
(def mpl (py/import-module "mypythonlib"))
(module-dict mpl)

The only .py file in my module is a 'test.py' that contains this code:
def test():
print("hello world")
My goal is to run the test.py from the module I have imported in my environment, then save the output to clojure variable.
My python function takes no arguments, and it seems the module is imported. I'm having trouble understanding how to call the function test() from clojure, or 'scan all the attributes' as you mentioned? Thanks for the help
from libpython-clj.

I am not sure the question is but it may also depend on if this is a namespace module or old-style module. The example I wrote is a namespace module.
from libpython-clj.
Awesome!!! I followed this example and was able to import my python module and get my 'hello world' to print!
Thank you a ton, this example helps explain away all my questions. I'll probably be back but I hope these issues help other people solve hurdles I'm facing when leaning this library. Your time is much appreciated @cnuernber !
