Manually scramble a vector in python... because why not

scramble.py

from random import randint

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


def swap(v, f, t):
    print(f, t)
    v[f] ^= v[t]
    v[t] ^= v[f]
    v[f] ^= v[t]


def scramble(v):
    lv = len(v)
    for i in range(lv-1):
        swap(v, i, randint(i+1, lv-1))


print(v)
scramble(v)
print(v)
