The Quick and Easy Way to Analyze Numpy Arrays

Image
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

What is Block-linking in Blockchain - Quick Tutorial

Satoshi Nakamoto created the first Blockchain project wished Bitcoin to be secure, anonymous and could work with no centralized intermediary. To achieve that, Nakamoto combined public-key cryptography, a distributed ledger, and a consensus algorithm. History of Blockchain  Nakamoto combined public-key cryptography, a distributed ledger, and a consensus algorithm. The groundwork for each component was painfully laid by people before him, such as Wei Dai, Nick Szabo, Hal Finney, and Adam Back. The Blockchain can sometimes refer to the combination of all three components or just the distributed ledger. Blockchain ideas As the name aptly describes, at the heart of the Blockchain there is a chain of blocks, each block containing read-only data that represents monetary transactions. Every time a new block is written, you need to reference the block that immediately precedes it – so, at any given point, you can track down the chain up to the very first block created.
