Below, I will roughly follow how I arranged the lecture on regular expressions, while also providing the relevant functions in the code. A regular expression is equivalent to some finite automaton.

I was involved in a recent discussion on the "best" way to remove a given parameter from a URL string. The conversation began with using string primitives to split and join the parameter, a method ...

How to use the regular expression functions provided by the ‘re’ library to match, search, and replace text in your Python programs. Regular expressions, or “regex,” is a system for finding complex ...

If you work with strings in your Python scripts and you're writing obscure logic to process them, then you need to look into regex in Python. It lets you describe patterns instead of writing ...

A python application to generate NFA and minimized DFA from regex. The application uses the Thompson's construction algorithm to generate the NFA and the subset construction algorithm to generate the ...
