What is the work of the “axis” keyword in the given code displayed in the screenshot?

what is the use of this and how it is working?

Hi Abhishek!

The `axis`

parameter defines the axis along which the means should be calculated. By default, the *mean* is computed of the flattened array. In version 1.7.0, if this is a tuple of ints, the mean is performed over multiple axes, instead of a single axis or all the axes as before. Here `axis = 0`

means along the column but `axis = 1`

will be working along the row. Notice that whenever you change the `axis`

values in mean function, you obtain a different answer.

Hope it helps. Happy Learning!
