How can I recreate Ruby's sort_by {rand} in python?-CodePudding

I have a line of code where can sort an array into random order:

someArray.sort_by {rand}

so in python, how can I convert to it to python code?

Maybe you are looking for this:

import random
l = [1, 2, 3]
# l is shuffled in place
random.shuffle(l)
# Print to see the shuffled l
print(l)

After reading the comments of @Aidis answer, it looks like that you want a cryptographically secure version of random.shuffle. That's what I came up with using urandom:

import os

array = [1,2,3,4,5,6,7,8,9]

array = sorted(array, key=lambda f: int.from_bytes(os.urandom(8), 'big'))

print(array)
