let's suppose you have to sort list X based on parallel list Y.

X = ["a", "b", "c", "d", "e", "f", "g", "h", "i"]
Y = [ 0, 1, 1, 0, 1, 2, 2, 0, 1]

Z = [x for _,x in sorted(zip(Y,X))]

print(Z) # ["a", "d", "h", "b", "c", "e", "i", "f", "g"]

For 2 list of same size and with any type

X = ["a", "b", "c", "d", "e", "f", "g", "h", "i"]
Y = [ 0,   1,   1,    0,   1,   2,   2,   0,   1]

Z = [x for _,x in sorted(zip(Y,X)), key=lambda pair: pair[0])]
print(Z)  # ["a", "d", "h", "b", "c", "e", "i", "f", "g"]

But this question can also mean that you want to sort a list with another one that have the same elements type but different size.

Exemple: you want to sort letters in a custom order

list_ = ['a', 'e', 'e', 'f', 'x', 'e', 'x']
order = 'e', 'f', 'x', 'a'

sorted_list = sorted(list_, key=order.index)
print(sorted_list)  # ['e', 'e', 'e', 'f', 'x', 'x', 'a']
