python-import

问题 I am reading this article. I am wondering why the below statement from the article is correct? As I can use the solution 1 - that is - python -m packA.a2 and it works fine. To give you some context, Solution 1 says: Use absolute imports rooted at the test/ directory (i.e. middle column in the table above). This guarantees that running start.py directly will always work. In order to run a2.py directly, run it as an imported module instead of as a script: change directories to test/ in the

问题 I'm creating a modular app using Flask blueprints feature. As a result, my directory structure is like this: project __init__.py config.py mould.py modules __init__.py core __init__.py core.py db.py models.py The modules directory here is not be confused with Python modules, they are for giving a modular structure to my project (core module, foo module, bar module, etc.). Now each folder in the modules directory (and a module inside it with same name such as core.core ) is dynamically

问题 Imports in an __init__.py seem to behave differently when the file is run, to when it is imported. If we have the following files: run.py : import test test/b.py : class B(object): pass test/__init__.py : from b import B print B print b If we run __init__.py we get an error as I expect: % python test/__init__.py <class 'b.B'> Traceback (most recent call last): File "test/__init__.py", line 6, in <module> print b NameError: name 'b' is not defined But if we run.py then we don't: % python run
