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

2 Best Ways to Concatenate Strings in Python

Concatenation of strings in Python is possible by using the plus and join method. You can also do it in other ways. But in my point of view, these two are the best methods. What are Strings? A string represents in quotes. Let us see the data. It can have all kinds of data. A lot you can do by manipulating strings. Concatenation is one. Example for strings  Stringa='Uncle' Stringb='is' Stringc='Married' Above example, you can see three strings. To make all these strings into a single, you need the concept of concatenation. What is string concatenation? String concatenation is a frequent activity in data science. Knowing this concept is helpful in your project and interviews as well. You can do it using the two best methods. One is you can use plus operator. For the other one, you can use the join method. #1: Using the plus operator Stringa='Uncle' Stringb='is' Stringc='Married' print(Stringa + ' ' + Stringb + ' ' + Stringc)
