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

6 Top Solidity Interview Questions

Solidity is the prime language to write the logic for smart contracts in the Ethereum blockchain. These are selected interview questions refresh before you take an interview. Solidity Interview Questions on Solidity 1. What is Solidity? A) Solidity is the main language that you can use to write programs in Blockchain, such as smart contracts. 2. Where the Solidity programs run in Ethereum? A). Those will run in EVM. You can also call it an Ethereum Virtual Machine. 3. What kind of logic a Smart Contract can contain? A contract in the sense of Solidity is a collection of code (its functions) and data (its state) that resides at a specific address on the Ethereum blockchain 4). Can the source code of smart contracts accessible to the outside world?  A). No, it is not possible to access the source code to the network. Also, there is limited access to one smart contract logic to the other smart contract logic. Eve, file systems, and other processes cannot access the source
