Indexing
Similar to Python lists(), NumPy arrays can be indexed using square brackets.
Indexing of arrays starts from 0.
Elements of the one-dimensional arrays or vectors are accessed by specifying the index number of the array enclosed within square brackets.
Elements of the two-dimensional arrays or matrices are accessed by ...
