Redundant importing of modules

[Jshgwave]

When writing a function that uses a module such as NumPy, it is tempting to include the statement "import numpy" or "import numpy as np" in the definition of the function, in case the  function is used in a script that hasn't already imported NumPy.

That could lead to the script issuing the "import numpy" command more than once.

Does Python know to disregard redundant "import" commands?
