Difference between “import X” and “from X import *”? [duplicate]

Answer 1

from X import * imports all elements from the module X into the current namespace. import X imports X but doesn't "merge" the namespaces. E.g.:

Module X:

def foo(): pass
BAR = 12

Your code:

from X import *
foo() # calls X.foo
print BAR # prints 12

Or:

import X
X.foo()
print X.BAR
