In python can anyone help me to implement function using the positional for loops in this def fixed_points(tup): """ Returns a copy of tup, including only the "fixed points". A fixed point of a tuple is an element that is equal to its position in the tuple. For example 0 and 2 are fixed points of (0,3,2). The fixed points are returned in the order that they appear in the tuple. Examples: fixed_points((0,3,2)) returns (0,2) fixed_points((0,1,2)) returns (0,1,2) fixed_points((2,1,0)) returns (1,) Parameter tup: the tuple to copy Precondition: tup is a tuple of ints """
