Create the following 2-dimensional array in python

`array([[ 1, 3, 5, 7], [ 9, 11, 13, 15], [17, 19, 21, 23], [25, 27, 29, 31], [33, 35, 37, 39]])`

Create an array of strings as follows:

`array(['Paris', 'Shanghai', 'New York', 'London', 'Mumbai'])`

Create a boolean array from the above array where the city value is either `London` or `Shanghai`, and assign it to a variable called `mask`.

Use the boolean array created to subselect rows of the array in part (a).
