python-importlib

问题 (Originally asked on r/learnpython, but figured I'd ask here too.) Since this problem came up while dealing with django, I'll explain in that context. So I have a django project folder, and some internal django apps living in that project folder, like this: project_module ├ apps │ ├ app_module1 │ │ ├ models.py │ │ └ ... │ ├ app_module2 │ └ ... ├ settings.py └ ... now the app_modules are available as project_module.apps.app_module1 and so on, but since there won't be anything colliding with

问题 I'm creating a _GeneratorContextManager with the following code. try: import importlib.resources as pkg_resources except ImportError: # Try backported to PY<37 `importlib_resources`. import importlib_resources as pkg_resources from . import file_resources package_path= pkg_resources.path(file_resources, "IWNLP.Lemmatizer_20181001.json") Here is the debugger view of the variable package_path. Now I want to pass the path of the file "IWNLP.Lemmatizer_20181001.json" to another function:

问题 I'm trying to retrieve metadata information for a python package given the name of the module. I can use importlib-metadata to retrieve the information, but in some cases the top-level module name is not the same as the package name. example: >>> importlib_metadata.metadata('zmq')['License'] Traceback (most recent call last): File "<stdin>", line 1, in <module> File "c:\Users\xxxxx\AppData\Local\Programs\Python\Python37\Lib\site-packages\importlib_metadata\__init__.py", line 499, in metadata

问题 I want to use importlib.import_module to import modules dynamically. My code like this: import os import importlib os.chdir('D:\\Python27\\Lib\\bsddb') m = importlib.import_module('db') print dir(m) I can to this successfully in the Python console. But if I run these code in a file C:\Users\Administrator\Desktop>python test.py , it can't work: Traceback (most recent call last): File "test.py", line 5, in <module> m = importlib.import_module("db") File "D:\Python27\lib\importlib\__init__.py",
