np.gradient() — A Simple Illustrated Guide

In Python, the numpy.gradient() function approximates the gradient of an N-dimensional array. It uses the second-order accurate central differences in the interior points and either first or second-order accurate one-sided differences at the boundaries for gradient approximation. The returned gradient hence has the same shape as the input array.  Here is the argument table of … Read more

Python __trunc__() Magic Method

Syntax and Definition object.__trunc__(self) The Python __trunc__() method implements the behavior of the math.trunc() function. For example, if you attempt to call math.trunc(x), Python will run the x.__trunc__() method to obtain the return value. We call this a “Dunder Method” for “Double Underscore Method” (also called “magic method”). To get a list of all dunder … Read more
