By the end of this project, you will use the python re package to create an application that verifies email form data from a file. Regular expressions are used to search for data patterns. They can be used to validate file or web data, and/or replace data when a match is found. In Python, the regular expression is compiled with a regular expression pattern. Then a string is passed to the regular expression engine where the search for the pattern match takes place. Note: This course works best for learners who are based in the North America region. We’re currently working on providing the same experience in other regions.

Skills you will develop

  • Email Validation

  • Python Regular Expression

  • Python Testing

  • Python Programming

  • Python File I/O
