What does each functionalities do?

1. Regex Generation for Numerical Range

Generate regex given a numerical range, So when given a new number between this range the regex will match.

Person who has motivated me to start this repository is listed in the acknowledgments.

Coded With Language

Getting Started

Simply install the package, import it in your python code and run the method needed. Look at the docstring or source code to understand what is happening.


Python 3.6 or greater


pip install regex-engine


1. Regex Generation for Numerical Range

You get what you give : If given numbers are integers you get a regex that will only match with integer and if floating-point numbers are given it only match with floating-point number.

Supports integer and floating-point numbers. It can even be a negative range.

from regex_engine import generator
generate = generator()
regex1 = generate.numerical_range(5,89)
regex2 = generate.numerical_range(81.78,250.23)
regex3 = generate.numerical_range(-65,12)

Example regex generated for 25-53


The regex might not be optimal but it will surely serve the purpose.

The problem of checking a number is within a range might have been simple if you didn't choose the regex path.
if a <= your_input_number <=b would have simply solved the same problem.

We dedicate this method in the package to the people who are pursuing a different path or thinking out of the box.
