pyrule
Deduplicate a list while keeping the first occurrence and its position — with
the one detail set() gets wrong: types are preserved.
Install
pip install pyrule
The problem
list(set([1, 1.0, True])) # -> [1] three rows silently become one
dedupe([1, 1.0, True]) # -> [1, 1.0, True]
In Python 1 == 1.0 == True, so naive deduplication loses records. For data
coming out of CSV, JSON or a database, those are three different values.
Usage
from pyrule import dedupe, dedupe_key
dedupe(["b", "a", "b"]) # ['b', 'a'] order kept
dedupe([{"a": 1}, {"a": 1}, {"a": 2}]) # two dicts kept
dedupe_key(1), dedupe_key(1.0) # ('int', '1'), ('float', '1.0')
Rules
| Input | Key |
|---|---|
str / int / float / bool / None |
(type name, repr) |
| anything else | canonical JSON, else repr |
Order is always preserved and the returned items are the originals, not copies.
