import
- Python code in one module gains access to the code in another module by the process of importing it.
- 1. it searches for the named module, then 2. it binds the results of that search to a name in the local scope.
Packages (regular packages & namespace packages)
- You can think of packages as the directories on a file system and modules as files within directories, but don’t take this analogy too literally since packages and modules need not originate from the file system.
- Packages are just a special kind of module. Specifically, any module that contains a __path__ attribute is considered a package.
Regular Packages
- A regular package is typically implemented as a directory containing an __init__.py file.
Name Packages
- Namespace packages may or may not correspond directly to objects on the file system; they may be virtual modules that have no concrete representation.
