python-scipyHow do I use Python Numpy to create a tutorial?

To create a tutorial using Python Numpy, you can use the following steps:

1. Import the Numpy module with import numpy as np
2. Create an array with arr = np.array([1,2,3,4])
3. Access elements of the array with arr[0]
4. Perform array operations with arr + 5
5. Create a multi-dimensional array with arr2 = np.array([[1,2,3],[4,5,6]])
6. Access elements of the multi-dimensional array with arr2[1,2]
7. Perform mathematical operations on the array with np.sum(arr2)

Example code

import numpy as np
arr = np.array([1,2,3,4])
arr[0]
arr + 5
arr2 = np.array([[1,2,3],[4,5,6]])
arr2[1,2]
np.sum(arr2)

Output example

1
array([6, 7, 8, 9])
6
21
