    because you import all from math by using this 'from math import * ' you don't have to write math.e use x = e or use 'import math' to write 'x = math.e'

    "from math import *" imports all of math's functions and properties into the current namespace. "import math" imports the math's namespace into the current name space. The first form doesn't have a math namespace, the second does. So math.e would only be used with the second form.
