Inverting permutations in Python

Question

I\'m new to programming, and I\'m trying to write a Python function to find the inverse of a permutation on {1,2,3,...,n} using the following code:

def inv(s         


        

Answer 1

Maybe there is a shorter way:

def invert(p):
    return [p.index(l) for l in range(len(p))] 

so that:

perm = [3, 0, 2, 1]; print(invert(perm))

returns

[1,3,2,0]
