A simple Python module for parsing human names into their individual components.

Project description

https://travis-ci.org/derek73/python-nameparser.svg?branch=master https://badge.fury.io/py/nameparser.svg

A simple Python (3.2+ & 2.6+) module for parsing human names into their individual components. The HumanName class splits a name string up into name parts based on placement in the string and matches against known name pieces like titles. It joins name pieces on conjunctions and special prefixes to last names like “del”. Titles can be chained together and include conjunctions to handle titles like “Asst Secretary of State”. It can also try to correct capitalization of all upper or lowercase names.

It attempts the best guess that can be made with a simple, rule-based approach. Unicode is supported, but the parser is not likely to be useful for languages that to not share the same structure as English names. It’s not perfect, but it gets you pretty far.

Quick Start Example

>>> from nameparser import HumanName
>>> name = HumanName("Dr. Juan Q. Xavier de la Vega III (Doc Vega)")
>>> name
<HumanName : [
    title: 'Dr.'
    first: 'Juan'
    middle: 'Q. Xavier'
    last: 'de la Vega'
    suffix: 'III'
    nickname: 'Doc Vega'
]>
>>> name.last
'de la Vega'
>>> name.as_dict()
{'last': 'de la Vega', 'suffix': 'III', 'title': 'Dr.', 'middle': 'Q. Xavier', 'nickname': 'Doc Vega', 'first': 'Juan'}
>>> name.string_format = "{first} {last}"
>>> str(name)
'Juan de la Vega'

3 different comma placement variations are supported for the string that you pass.

  • Title Firstname “Nickname” Middle Middle Lastname Suffix
  • Lastname [Suffix], Title Firstname (Nickname) Middle Middle[,] Suffix [, Suffix]
  • Title Firstname M Lastname [Suffix], Suffix [Suffix] [, Suffix]

The parser does not make any attempt to clean the data. It mostly just splits on white space and puts things in buckets based on their position in the string. This also means the difference between ‘title’ and ‘suffix’ is positional, not semantic. (“Pre-nominal” and “post-nominal” would probably be better names.)

>>> name = HumanName("1 & 2, 3 4 5, Mr.")
>>> name
<HumanName : [
    title: ''
    first: '3'
    middle: '4 5'
    last: '1 & 2'
    suffix: 'Mr.'
    nickname: ''
]>

Customization

Your project may need a bit of adjustments for your dataset. You can do this in your own pre- or post-processing, by customizing the configured pre-defined sets of titles, prefixes, etc., or by subclassing the HumanName class. See the full documentation for more information.
