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

How to Use Python Try and Except Logic Correctly

In Python, you can avoid exceptions using Try and Except logic. The Error-free programs save a lot of time. Also, you can keep away defects in production.   How to Use Python Try and Except Logic Correctly In Python, you can handle un-known errors by using TRY and EXCEPT logic. If the programmer does not take care of this, the default is for  Python to print  an error message and stops execution.  So the responsibility of a programmer is upfront he/she has to find errors and handle them correctly. It is possible if you use the  TRY and EXCEPT. Python Syntax for Try and Except. try:       c = a/b except:       c = 1000000 Try ends with ':' it says that Try block start here. In this block, you can write actual logic. The Except: is another block. That means in this block programmer can specify some value. And that value populates when any error happens. Try and Except Examples. Example: 1. Below is the example to give the expected error in except. try:       c = a/b except Ze
