Mirror Inverse Program in python

# Python 3 implementation of the approach
 
# Function that returns true if
# the array is mirror-inverse
def isMirrorInverse(arr, n) :
 
    for i in range(n) :
 
        # If condition fails for any element
        if (arr[arr[i]] != i) :
            return False;
     
    # Given array is mirror-inverse
    return true;
 
# Driver code
if __name__ == "__main__" :
     
    arr = [ 1, 2, 3, 0 ];
     
    n = len(arr) ;
    if (isMirrorInverse(arr,n)) :
        print("Yes");
    else :
        print("No");
