More Data Structures

More Data Structures

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

Data Structures

id

SemVer

Class for easy creation of semantic version numbers.

network

URL

Class for easy (unvalidated) URL construction.

time

Timer

Context manager for timing a block of code.

Getting Started

% pip install more-ds

>>> from more_ds.network 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

Or

from time import sleep

from more_ds.time import Timer
with Timer() as t:
    # sleep for half a second
    sleep(.5)

print(t.elapsed)  # -> 0:00:00.501864

Or

>>> from more_ds.id import SemVer
>>> old = SemVer("v3.1.4")
>>> new = SemVer("3.2")
>>> old
SemVer("3.1.4")
>>> new
SemVer("3.2.0")
>>> old == new
False
>>> old < new
True
>>> old > new
False
>>> repr(old)
'SemVer("3.1.4")'
>>> repr(new)
'SemVer("3.2.0")'
>>> isinstance(old, str)
True

Origin

The projected started with the need to extract the simplest of classes from an existing 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 inspired by the wonderful More Itertools library.
