The import and from-import statements are somewhat confusion for beginners to Python.
Here we will discuss some common issues related to import and from-import.
Python have 3 different ways to import modules.
1. import statement
2. from statement
3. builtin __import__ function

import X imports the module X, and creates a reference to that module in the current namespace.So you have to use X.name to refer to things defined in module X.
from X import * imports the module X, and creates references in the current namespace to all public objects defined by that module (that is, everything that doesn’t have a name starting with “_”) hence you can simply use a plain name to refer to things defined in module X. Since X itself is not defined, so X.name doesn’t work.
from X import a, b, c imports the module X, and creates references in the current namespace to the given objects i.e a,b,c.
