How does Python handle multiple imports?
As others have pointed out, Python maintains an internal list of all modules that have been imported. When you import a module for the first time, the module (a script) is executed in its own namespace until the end, the internal list is updated, and execution of continues after the import statement.
How many types of imports are there in Python?
There are generally three groups: standard library imports (Python’s built-in modules) related third party imports (modules that are installed and do not belong to the current application) local application imports (modules that belong to the current application)
How to import functions from other projects in Python?
That project you make into a package, which you can work on separately. You then release version of it, and reuse them in your other projects. It is important that you have versions that you “release” so that you can keep track of which version of the module each project uses.
How to share common code among a family of Python scripts?
Within each subproject the import root directory is projectroot so you have to use absolute imports or explicit relative imports within the project itself. The other downside is that it requres the, perhaps, non-obvious -m flag to run the applications. Thanks for contributing an answer to Stack Overflow!
Can a script run a function in Python?
That is, all it does is import the appropriate “scriptN_main” module and run a function in it. Using a simple script may also have some small benefits for script startup speed, since the main module can have its compiled bytecode cached to a .pyc file, while scripts are never cached.
What happens when a module is imported in Python?
When a module is imported, Python runs all of the code in the module file. When a package is imported, Python runs all of the code in the package’s __init__.py file, if such a file exists. All of the objects defined in the module or the package’s __init__.py file are made available to the importer. Basics of the Python import and sys.path
