What is reusability in Python?
Reusing code is key to building a maintainable system. And when it comes to reusing code in Python, it all starts and ends with the humble function. Take some lines of code, give them a name, and you’ve got a function (which can be reused).
What are Python modules for?
A module allows you to logically organize your Python code. Grouping related code into a module makes the code easier to understand and use. A module is a Python object with arbitrarily named attributes that you can bind and reference. Simply, a module is a file consisting of Python code.
Is it pythonic to import inside functions in Python?
FWIW, there are cases where it makes sense to import inside a function. For example, if you want to set the language in cx_Oracle, you need to set an NLS _ LANG environment variable before it is imported. Thus, you may see code like this: I’ve broken this rule before for modules that are self-testing.
Where does a Python module go in a repository?
It should not be tucked away: If your module consists of only a single file, you can place it directly in the root of your repository: Your library does not belong in an ambiguous src or python subdirectory. Lawyering up. This is arguably the most important part of your repository, aside from the source code itself.
What should be at the root of a Python repository?
Package and distribution management. If your module package is at the root of your repository, this should obviously be at the root as well. Development dependencies. A pip requirements file should be placed at the root of the repository.
Is there such thing as ravioli code in Python?
Ravioli code is more likely in Python: it consists of hundreds of similar little pieces of logic, often classes or objects, without proper structure. If you never can remember, if you have to use FurnitureTable, AssetTable or Table, or even TableNew for your task at hand, then you might be swimming in ravioli code.
