Three reasons I stay away from coffee:
-

I don’t like the taste
-
It fails the Ames test
Note: The Ames test is a widely used assay to detect substances that can cause genetic mutations. If coffee "fails" this test in its raw form, it typically refers to unbrewed or concentrated extracts — brewed coffee usually does not show mutagenic activity due to dilution and chemical transformation during roasting.
Python

The __new__ method is a low-level constructor that’s usually hidden from view. The __init__ method is called after __new__ and is used to initialize instance attributes.
self is just like this which is used to refrence the current instance of the class.

Here a+1 is computed for each element.
Lambda
Lambda functions originate from lambda calculus. They provide a shorthand way to define small, anonymous functions:
