Should you call dunder methods (Double leading and trailing UNDERscores)
manually? For example:
my_number.__add__(another_number)
The short answer is:
NO! In general, you shouldn't do it.
Guido recently commented:
I agree that one shouldn't call __init__ manually (and in fact Python
always reserves the right to have "undefined" behavior when you
define or use dunder names other than documented).
so unless documented as safe to use manually, you should assume that it
is not.
