None of the responses so far actually give you what you asked for, as 
they assume you didn't mean 'array' but meant 'list.'  I suspect they're 
right, but here's an approach for array.array.

If you really want a multiprocess.Array, or numpy's array, please say 
so, and somebody'll tell you how to put random numbers in one of them.



import array
import random

floats = (random.random() * 5 for _ in xrange(100))
data = array.array('d', floats)

print data
print type(data)
