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 Create an Array and Its Types in Python

Python supports various array types. Here is a list of arrays and how to create examples for your reference. 

What is an array?

Python array is a class that mimics the array type of other languages and offers efficiency in storage, exchanging that for flexibility.

How to create an array

Here is the syntax to create an array:

data = array('f', [12.8, 5.4, 8.0, 8.0, 9.21, 3.14])

It creates an array of 6 floating point numbers; the type is indicated by the 'f' as the first parameter to the constructor. This concept is unlike the Python norm of types being dynamic and malleable. An array is an array of one kind of thing, and an array can only hold a restricted set of types.

Array types

Types of arrays

Here is a list of arrays:

'b' A C++ char type
'B' A C++ unsigned char type
'i': A C++ int type
'l': A C++ long type
'f': A C++ float type
'd': A C++ double type

What is an array type?

Arrays are class objects and are provided in the built-in module array, which must be imported:

from array import array

An array is a sequence type and has the basic properties and operations that Python provides for all sequence types. Array elements can be assigned to and can be used in expressions, and arrays can be searched and extended like other sequences.
