what is the basic difference between the commands
import pylab as *

Are you sure you don't mean

from pylab import *

???

The other form won't work because * is not a valid name in Python.
You should ghet a syntax error.

import matplotlib.pyplot as plt

This is just an abbreviation to save typing matplotlib.pyplot
in front of every reference to the module names.

import numpy as np

as above

import numpy as *

again an error.
