python arrays numpy minimum

how would one go about finding the minimum value in an array of 100 floats in python? I have tried minindex=darr.argmin() and print darr[minindex] with import numpy (darr is the name of the array)

but i get: minindex=darr.argmin()

AttributeError: 'list' object has no attribute 'argmin'

what might be the problem? is there a better alternative?

thanks in advance

Python has a min() built-in function:

>>> darr = [1, 3.14159, 1e100, -2.71828]
>>> min(darr)
-2.71828
