Adds a person provider for the si_LK locale with 457 Sinhala first names (246 male, 211 female) and 40 common Sri Lankan surnames, all in Sinhala script. First name data comes from the MIT-licensed dataset at https://github.com/TharindaDilshan/predicting-gender-in-sinhala-names, normalized to NFC and deduplicated. Surnames were curated and verified by a native speaker. Prefixes are intentionally omitted: Sinhala honorifics (mahatha/miya) are placed after the name, which the prefix format cannot express.

What does this change
Adds
faker/providers/person/si_LK/— the first provider for the Sinhala (Sri Lanka)locale — plus a
TestSiLKtest class intests/providers/test_person.py.all in Sinhala script
prefixesare intentionally omitted: Sinhala honorifics (මහතා/මිය) are placedafter the name, which the prefix format cannot express
What was wrong
Faker has no locale for Sri Lanka (~22M people). The nearest locales
(
ta_IN,hi_IN,ne_NP) don't cover Sinhala names.How this fixes it
Introduces the si_LK locale following the structure of existing locales such as
ta_INandne_NP. First-name data comes from the MIT-licensed dataset athttps://github.com/TharindaDilshan/predicting-gender-in-sinhala-names (credited in
the code), normalized to NFC and deduplicated. Surnames were curated by me; I am a
native Sinhala speaker and verified all name data, including zero-width-joiner
conjuncts (e.g. ප්රනාන්දු, වික්රමසිංහ).
I plan follow-up PRs for
ssn(Sri Lankan NIC numbers — I maintainslnic),
phone_number, andaddress.Fixes #2429
AI Assistance Disclosure (REQUIRED)
I used Claude Code (Claude Fable 5) for scaffolding, data-cleaning scripts, and test
wiring. All name data was reviewed and verified by me as a native speaker; no names
are AI-generated.
