Python library to validate usernames suitable for use in public facing

applications where use can choose login names and sub-domains.

## Features

-   Provides a default regex validator

-   Validates against list of [banned

    words](https://github.com/theskumar/python-usernames/blob/master/usernames/reserved_words.py)

    that should not be used as username.

-   Python 3.8+

## Installation

    pip install python-usernames

## Usages

```python

from python_usernames import is_safe_username

>>> is_safe_username("jerk")

False  # contains one of the banned words

>>> is_safe_username("handsome!")

False  # contains non-url friendly `!`

```

**is\_safe\_username** takes the following optional arguments:

-   `whitelist`: a case insensitive list of words that should be

    considered as always safe. Default: `[]`

-   `blacklist`: a case insensitive list of words that should be

    considered as unsafe. Default: `[]`

-   `max_length`: specify the maximun character a username can have.

    Default: `None`

- `regex`: regular expression string that must pass before the banned

:   words is checked.

The default regular expression is as follows:

    ^                       # beginning of string

    (?!_$)                  # no only _

    (?![-.])                # no - or . at the beginning

    (?!.*[_.-]{2})          # no __ or _. or ._ or .. or -- inside

    [a-zA-Z0-9_.-]+         # allowed characters, atleast one must be present
