PYTHON ONLY! PLEASE FOLLOW THE FORMAT/DIRECTIONS GIVING ONLY! SO I CAN LEARN.

Write a program that takes three floats x, y, and z from the command line, reads from standard input a sequence of coordinates (x_, y_i, z_i), and writes the coordinates of the point closest to (x, y, z). Recall that the square of the distance between (x, y, z) and (x_i, y_i, z_i) is (x - xi)^2 + (y - yi)^2 + (z - z_i)^2. For efficiency, do not use either math. squareroot () or the operator. # closest.py: takes three floats x, y, and z from the command line, reads from # standard input a sequence of coordinates (x_i, y_i, z_i), and writes the # coordinates of the point closest to (x, y, z). import stdio import sys # Read x, y, and z from command line, as floats, x = ... y =. .. z =. .. # Closest squared-distance so far, initialized to infinity. bestDist2 = float('inf') # Read coordinates (xi, yi, zi) from standard input and calculate its # squared-distance to the point (x, y, z). Check if that value is smaller # than bestDist2, and if so, update bestDist2 to the new value, and # let (bestx, esty, bestz) be (xi, yi, zi). while
