Simple, robust email validation

Project description

Latest version released on PyPI ci Test coverage downloads

Getting Started

pyIsEmail is a no-nonsense approach for checking whether that user-supplied email address could be real. Sick of not being able to use email address tagging to sort through your Bacn? We can fix that.

Regular expressions are cheap to write, but often require maintenance when new top-level domains come out or don’t conform to email addressing features that come back into vogue. pyIsEmail allows you to validate an email address – and even check the domain, if you wish – with one simple call, making your code more readable and faster to write. When you want to know why an email address doesn’t validate, we even provide you with a diagnosis.

Install

Install from PyPI using pip, a package manager for Python.

$ pip install pyIsEmail

Don’t have pip installed? Try installing it by running this from the command line:

$ curl https://raw.github.com/pypa/pip/master/contrib/get-pip.py | python

Or you can download the source code (zip) for pyIsEmail and then run:

$ python setup.py install

You may need to run the above commands with sudo.

Usage

For the simplest usage, import and use the is_email function:

from pyisemail import is_email

address = "test@example.com"
bool_result = is_email(address)
detailed_result = is_email(address, diagnose=True)

You can also check whether the domain used in the email is a valid domain and whether or not it has a valid MX record:

from pyisemail import is_email

address = "test@example.com"
bool_result_with_dns = is_email(address, check_dns=True)
detailed_result_with_dns = is_email(address, check_dns=True, diagnose=True)

These are primary indicators of whether an email address can even be issued at that domain. However, a valid response here is not a guarantee that the email exists, merely that is can exist.

If you want to limit using a gTLD as the domain part of the email address, you can do so with a flag:

from pyisemail import is_email

address = "thiswont@workatall"
bool_result_with_check = is_email(address, allow_gtld=False)
detailed_result_with_check = is_email(address, allow_gtld=False, diagnose=True)

In addition to the base is_email functionality, you can also use the validators by themselves. Check the validator source doe to see how this works.

Uninstall

Want to get rid of pyIsEmail? Did you install with pip? Here you go:

$ pip uninstall pyIsEmail

Acknowledgements

The base ParserValidator is based off of Dominic Sayersis_email script. I wanted the functionality in Python, so I ported it from the original PHP.
