Example 3: Standard Deviation of Columns in NumPy ArrayThe following Python code shows how to find the standard deviation of the columns of a NumPy array.To do this, we have to set the axis argument equal to 0:print(np.std(my_array, axis = 0)) # Get standard deviation of array ...
Example 1 explains how to compute the variance of all values in a NumPy array. In order to achieve this, we can use the var function of the NumPy library as shown in the following Python code: print(np.var(my_array))# Get variance of all array values# 5.466666666666667 ...

I just wanted to show you that it's possible, using the easiest possible example. While one can handle HTTP tasks with it, it's not fun and requires a lot of boilerplate code that we don't need to write - performing HTTP requests is a solved problem, and in PHP (and many other ...
Example code for the book Fluent Python, First Edition by Luciano Ramalho (O'Reilly, 2015). Code here may change and disappear without warning. If a piece of code is not yet in the ebook, it's likely to be broken. A major reorganization may happen when the last chapter is done. ...
