python-import

问题 I am trying to use Python unittest and relative imports, and I can't seem to figure it out. I know there are a lot of related questions, but none of them have helped so far. Sorry if this is repetitive, but I would really appreciate any help. I was trying to use the syntax from PEP 328 http://www.python.org/dev/peps/pep-0328/ but I must have something wrong. My directory structure is: project/ __init__.py main_program.py lib/ __init__.py lib_a lib_b tests/ __init__.py test_a test_b I run my

问题 I've been struggling with imports in my package for the last hour. I've got a directory structure like so: main_package | | __init__.py | folder_1 | | __init__.py | | folder_2 | | | __init__.py | | | script_a.py | | | script_b.py | | folder_3 | | __init__.py | | script_c.py I want to access code in script_b.py as well as code from script_c.py from script_a.py . How can I do this? If I put a simple import script_b inside script_a.py , when I run from main_package.folder_1.folder_2 import

问题 I am developing several Python projects for several customers at the same time. A simplified version of my project folder structure looks something like this: /path/ to/ projects/ cust1/ proj1/ pack1/ __init__.py mod1.py proj2/ pack2/ __init__.py mod2.py cust2/ proj3/ pack3/ __init__.py mod3.py When I for example want to use functionality from proj1 , I extend sys.path by /path/to/projects/cust1/proj1 (e.g. by setting PYTHONPATH or adding a .pth file to the site_packages folder or even

问题 How do I define the function in the importer so that it is visible inside imported?

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 6 years ago . I'm new to Python coding and I'm coming from a PHP background. I'm curious why you have to 'import' functions at the top of you python script. In PHP you can simply use the function such as: sleep(10); The above would cause the script to sleep for 10 seconds. However, to do the
