nameparser 1.2.0

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

A simple Python (3.10+) module for parsing human names into their individual components.

• hn.title

• hn.first

• hn.middle

• hn.last

• hn.suffix

• hn.nickname

• hn.surnames (middle + last)

• hn.initials (first initial of each name part)

Supported Name Structures

The supported name structure is generally “Title First Middle Last Suffix”, where all pieces are optional. Comma-separated format like “Last, First” is also supported.

1. Title Firstname “Nickname” Middle Middle Lastname Suffix

2. Lastname [Suffix], Title Firstname (Nickname) Middle Middle[,] Suffix [, Suffix]

3. Title Firstname M Lastname [Suffix], Suffix [Suffix] [, Suffix]

Instantiating the HumanName class with a string splits on commas and then spaces, classifying name parts based on placement in the string and matches against known name pieces like titles and suffixes.

It correctly handles some common conjunctions and special prefixes to last names like “del”. Titles and conjunctions can be chained together to handle complex titles like “Asst Secretary of State”. It can also try to correct capitalization of names that are all upper- or lowercase names.

It attempts the best guess that can be made with a simple, rule-based approach. Its main use case is English and it is not likely to be useful for languages that do not conform to the supported name structure. It’s not perfect, but it gets you pretty far.

Installation

pip install nameparser

If you want to try out the latest code from GitHub you can install with pip using the command below.

pip install -e git+https://github.com/derek73/python-nameparser.git

If you need to handle lists of names, check out namesparser, a compliment to this module that handles multiple names in a string.

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'}
>>> str(name)
'Dr. Juan Q. Xavier de la Vega III (Doc Vega)'
>>> name.string_format = "{first} {last}"
>>> str(name)
'Juan de la Vega'

The parser does not attempt to correct mistakes in the input. 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. “Dr” is a title when it comes before the name and a suffix when it comes after. (“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 some adjustment 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.
