The Quick and Easy Way to Analyze Numpy Arrays

The quickest and easiest way to analyze NumPy arrays is by using the numpy.array() method. This method allows you to quickly and easily analyze the values contained in a numpy array. This method can also be used to find the sum, mean, standard deviation, max, min, and other useful analysis of the value contained within a numpy array. Sum You can find the sum of Numpy arrays using the np.sum() function.  For example:  import numpy as np  a = np.array([1,2,3,4,5])  b = np.array([6,7,8,9,10])  result = np.sum([a,b])  print(result)  # Output will be 55 Mean You can find the mean of a Numpy array using the np.mean() function. This function takes in an array as an argument and returns the mean of all the values in the array.  For example, the mean of a Numpy array of [1,2,3,4,5] would be  result = np.mean([1,2,3,4,5])  print(result)  #Output: 3.0 Standard Deviation To find the standard deviation of a Numpy array, you can use the NumPy std() function. This function takes in an array as a par

Python Interface Vs. Class: What's the Difference

Here are the differences between Class and Interface in Python. Python class can have all concrete methods. But interface does not have single concrete method. Here you'll know about What's abstract method Abstract Class: How to Create it Rules to Write an Interface How to Create Abstract Class How to Create an Interface What's abstract method The abstrcat method is one which does not have body. from abc import ABC, abstract method class name_class(ABC): # abstract class @abstractmethod def name_method(self): #abstract method without body pass The interface is used when all the features are needed to be implemented differently for different objects. Rules to Write an Interface All methods of an interface should be abstract. You cannot create an interface object. If any class implements an interface, then you need to define all the methods given in that interface in child class. You need to declare all methods as abstract if that class does not implement the interface How to
