Gain insights into Python's regular expressions with practical examples, web scraping projects, coding exercises, and beginner-friendly lectures. Delve into real-world data and enhance your Python skills effectively.

Regex with Python? Many of you do not find this combination easy, which partly happens because of the Python's obfuscated regex documentation too! In this course, to make your life easy, I have used some real-world examples.  The goals are:

- Teach you how to use the Python regular expressions (re) module and relevant functions by running interactive examples;
- Educate you to deal with projects with real world data examples (e.g., pdf and web scraping, more coming soon!);
- Challenge you with coding exercises and quizzes; and
- Beginner friendly video lectures to explain the basic REGEX concepts.

This is a short course,  should be pretty quick and easy to complete. However, it assumes that you have basic Python skills (see the other Python courses on this platform). This course should get you going with Python Regex in less than 30mins. This course is a core component of the 'Learn Scientific Programming' project.

Python Regular Expressions with Data Scraping Projects

# PDF scraping example:

In this project we will use a pdf file (see the screenshot below) from the diabetes.org website. Our goal is to list all the equipment models developed by the manufacturers names containing the word `tandem` (case insensitive).


# Input file

You can download the input file from here: [data.pdf](http://main.diabetes.org/dforg/pdfs/2015/2015-cg-insulin-pumps.pdf).

# Solution

A complete explanation of the Python code is **out of the scope** for this course (hint: learn the Python module `pdfquery`). It should be easy enough for you to understand how we capture the `porduct_name` from the pdf file using bounding box function `LTTextLineHorizontal:in_bbox("40, 48, 181, 633")` and then iterate over the products and search using regex and then only print the `Tandem` Manufacurers.



In this project we use regex to extract a list of items from a pdf file.
