Let's practice NumPy. Mastering NumPy now will make our work much easier in the future, when we start doing machine learning in Python.
Download the jupyter notebook from here and follow the instructions.
We have learned the basics of NumPy. It makes our work in Python much more efficient because it introduces a new data type
np.array. Python can work more efficiently and faster with this type.
We cannot use
np.arrayall the time. Sometimes it's more efficient to use
dictionary. For example, if we want to iterate over the values in a variable.
