So far in this book, we encountered several convenient functions for intializing arrays. The full() and full_like() functions were recently added to NumPy to make initialization even easier.

The following short Python session shows (abbreviated) documentation for these two functions:

$ python
>>> import numpy as np
>>> help(np.full)
Return a new array of given shape and type, filled with `fill_value`.
>>> help(np.full_like)

Return a full array with the same shape and type as a given array.
