Here’s a list of commonly asked questions. If you can’t find what you’re looking for here you may want to consider asking a question on StackOverflow.

Why should I use is-number?

You probably shouldn’t! This project was built as part of a blog post series on creating an open source Python project from scratch.

It contains a trivially small amount of code and is poking a bit of tongue-in-cheek fun at the JavaScript community who are known for publishing very small packages on NPM and then having half the internet break if one package is taken down.

If you want to check if something is a number in your Python code you should probably just write your own utility function like this instead of adding another dependency.

def is_number(in_value):
        return True
    except (ValueError, TypeError):
        return False
