**Python Multi-Dimensional Arrays or Matrices**

Since a tuple is basically like an array that is not modifiable, we'll treat it almost the same as a list. Sorting a Python List the Simple Way. Okay, so if you only want to sort a list of numbers, Python has a built in function that does all the hard work for you. Say we have a list of numbers: 1 >>> a = [3, 6, 8, 2, 78, 1, 23, 45, 9] And we want to sort them in ascending order. All we do is... a = arange(10,0,-2) #a = [10 8 6 4 2] And finally, array can be used to convert a list to an array. For instance, when reading from a file, you can create an empty list and take advantage of the append command and lists not having a fixed size.

Two dimensional array is an array within an array. It is an array of arrays. In this type of array the position of an data element is referred by two indices instead of one. So it represents a table with rows an dcolumns of data. In the below example of a two dimensional array, observer that each array element itself is also an array.... I am new to python coming from a Java background and am trying to create two arrays from a single array where the odd indexs are put in one array and the even index are put into another.

## How To Create A 2 By 2 Array In Python

For technical computing, I recommend the use of Numpy arrays instead of the native Python arrays. Indeed, Numpy is used by most scientific packages in Python, including Pandas, Scipy, and Scikit-Learn. Numpy provides a matrix class that can be used to mimic Octave and Matlab operations. For instance, one can create matrices using a similar syntax:

- It is no longer recommended to use this class, even for linear algebra. Instead use regular arrays. The class may be removed in the future. Returns a matrix from an array-like object, or from a string of data. A matrix is a specialized 2-D array that retains its 2-D nature through operations. It has
