I want to create a python list with elements 1..15, but these numbers should be in random order. e.g. [3,15,10,4....]. What is the best Pythonic way to get this result?

You can use **shuffle() **function of random or **permutation()** function of numpy.random. See the following examples:

>>> t=[i for i in range(15)]

>>> random.shuffle(t)

>>> t

[5, 6, 12, 1, 9, 14, 7, 11, 3, 0, 4, 8, 13, 2, 10]

>>> import numpy

>>> numpy.random.permutation(15)

array([ 9, 14, 12, 13, 7, 0, 6, 3, 5, 10, 8, 1, 11, 4, 2])

>>>

For shuffle(), you need to declare the list first, but for permutation, you don't have to declare the list in advance.
