Reordering the list based on values from another list?

How to reorder the first list based from another list in Python?

I cannot reorder the 2 list so here's my code:

import random
numElements1 = int(input("Enter the number of elements for first list: "))
numElements2 = int(input("Enter the number of elements for second list: "))

randomlist = random.sample(range(10, 99), numElements1)
print(randomlist)

randomlist2 = random.sample(range(10, 99), numElements2)
print(randomlist2)

You can use sorted() with zip()

arr, index = map(list, zip(*sorted(zip(arr, index), key=lambda x: x[1])))

print(arr) #[40, 60, 90, 50, 70]
print(index) #[0, 1, 2, 3, 4]

a={}
for i in index:
    a[i]=randomlist[i]

for i,j in sorted(a.items()):
    out_index.append(i)
    out_arr.append(j)
