Error: Module smtplib Has No Attribute SMTP

What's Causing This Error?

This error occurs when Python discovers a circular dependency with the smtplib module.

For example, if your email sending script were named smtplib.py or email.py, Python would try to import your file when it executes the import statement for the smtplib library. As a result, it creates a partially initialized module, and if your script does not have an attribute named smtp, you will run into this error.

Solution - Here's How To Resolve It

To resolve this error, rename your email sending script to a name apart from smtplib.py or email.py, as these are internal script files that make up the smtplib module. Doing so would help Python import the correct library and resolve the error.
