What does a . in an import statement in Python mean?
(3 answers)
Closed 4 years ago.
For what i can use the "." in import module. I meet it in sklearn library. It looks like:
from .externals import six
The . is a shortcut that tells it search in current package before rest of the PYTHONPATH. So, if a same-named module Recipe exists somewhere else in your PYTHONPATH, it won't be loaded.

What's the difference between a Python module and a Python package?

I can't understand how the python import works for big projects on the Github.
Everyone knows the import statement - "from packageName import moduleName".
But for some big projects, for example Django.
I've got tutored "from django.urls import path". (https://docs.djangoproject.com/en/3.2/topics/http/urls/)
But couldn't find any path.py file under /django/urls directory from its Github structure. (https://github.com/django/django/tree/main/django/urls)
Did I miss any advanced import mechanism?
If you look at __init__.py, it imports the name path from conf.py. This makes path available as a variable in the django.urls module which can be imported.

Is there a way to programmatically find the location of a python package once it is imported?
For example:
import os
import pandas
os.get_package_directory(panda)
>>> C:\Users\username\miniconda3\pkgs\pandas-1.0.5-py37h47e9c7a_0
It's been a while since I've done this, but try this:
import pandas
print(pandas.__file__)

How can I import a module dynamically given the full path?
(35 answers)
Closed 3 years ago.
I want to import some files/modules from other directory.
I have placed an init.py in the directory but still not able to import the files/modules.
I am using Pycharm 2019.
I want to use init.py only method and not the sys.path.append.
thanks in Advance!
there are multiple ways to do that, I'll name two -
import sys
sys.path.insert(0, 'path/to/your/py_file')
import py_file
is relatively easy, and another one is if you're using pycharm just mark the directory of which you want to import from as a sources root.

How to list imported modules?
(10 answers)
Closed 3 years ago.
In Python calling the import function brings in a module to give a program access to its namespace of classes, functions and variables.
import os
import sys
print(os.name)
print(sys.implementation)
Is there a way to list which modules have already been imported in a program?
>>> list_imports()
sys
os
And if so, is there a way to figure out the version of the imported module?
sys.modules is the closest you'll get. Modules following spec will have a __version__ attribute.
Just use sys library
import sys
sys.modules.keys()
