/Python/Python arithmetic operation with list

Python arithmetic operation with list

#If you're going to be doing lots of array operations,
#then you will probably find it useful to install Numpy.
#Then you can use ordinary arithmetic operations element-wise on arrays,
#and there are lots of useful functions for computing with arrays.
>>> import numpy
>>> a = numpy.array([111,222,333])
>>> a * 3
array([333, 666, 999])
>>> a + 7
array([118, 229, 340])
>>> numpy.dot(a, a)
172494
>>> numpy.mean(a), numpy.std(a)
(222.0, 90.631120482977593)
