More Data Structures

More Data Structures or more-ds for short, provides simple and convenient Python data structures.

Origin

The projected started with the need to extract the simplest of classes from an exitsting open source library, nwa-stdlib. That library primarily contained code that was rather specific to the organization that created the library. However, the URL class was a tiny convenience data structure, with broader applicability, that took the chore out of programmatically creating URLs. By extracting that class into a separate project, one that is specifically focussed on convenient data structures, it hopefully attracts a broader set of users that would otherwise don’t feel comfortable including nwa-stdlib as a whole.

The project’s name was inpired by the wonderful More Itertools library.

Data Structures

There is currently one data structure available (more to follow):

• URL

URL

The URL class is a str (overrides it). Hence, can be used anywhere a regular string is used. It overrides two magical methods that correspond to the / and // operators.

The / operator is used to concatenate separate path components of a URL. The // operator is used to append a query string by supplying it with a dictionary.

An example should make this clear:

>>> from more_ds.network.url import URL
>>> base_url = URL("http://example.org/")
>>> api_url = base_url / "api"
>>> url = api_url / "ip" / "address" // dict(version=4)
>>> print(url)
http://example.org/api/ip/address?version=4

When adding path components, the / operator will insert or remove redundant slashes where necessary. The // automatically take cares of properly URL encoding the keys and values.
