IsClose() in python

This post tries to answer whether given numbers are comparatively close to each other. This can help if you are using Python for data science or in the area of computer vision doing computing with images. A quick stack-overflow search shows discussion around finding “nearest” value from a set of given values for any given number [1] [2] [3]. However, there could be a need to limit how much further the nearest number could be. I’d call this limit a “threshold”.

Quite a few times, in my Python (esp. in computer vision related) programming I come across scenarios when I want to tell if the two numbers are close to each other. Some might ask, “Well define close!?” or “How close?”, well … comparatively close.
