It’s a new feature called Modules or “semantic import”. There’s more info in the WWDC 2013 videos for Session 205 and 404. It’s kind of a better implementation of the pre-compiled headers. You can use modules with any of the system frameworks in iOS 7 and Mavericks. Modules are a packaging together of the framework … Read more
There is no import aliasing mechanism in Java. You cannot import two classes with the same name and use both of them unqualified. Import one class and use the fully qualified name for the other one, i.e. import com.text.Formatter; private Formatter textFormatter; private com.json.Formatter jsonFormatter;

EDIT: There are better/more coherent answers to this question in other questions: Sibling package imports Relative imports for the billionth time Why doesn’t it work? It’s because python doesn’t record where a package was loaded from. So when you do python -m test_A.test, it basically just discards the knowledge that test_A.test is actually stored in … Read more
The only problem with it is that it clutters your local namespace.

First, import function from file.py: from file import function Later, call the function using: function(a, b) Note that file is one of Python’s core modules, so I suggest you change the filename of file.py to something else. Note that if you’re trying to import functions from a.py to a file called b.py, you will need … Read more
This is a default import: // B.js import A from ‘./A’ It only works if A has the default export: // A.js export default 42 In this case it doesn’t matter what name you assign to it when importing: // B.js import A from ‘./A’ import MyA from ‘./A’ import Something from ‘./A’ Because it … Read more
