General Numerical Python question

[2mc]

Generally speaking, if one had a list (from regular Python) and an
array (from Numerical Python) that contained the same number of
elements, would a While loop or a For loop process them at the same
speed?  Or, would the array process faster?

I'm new to Python, so my question may expose my ignorance.  I
appreciate anyone's effort to help me understand.

Thanks.  It is much appreciated.
