    4. Writing to a file: print and file= [fileio4.py]
  4. How to Write a Program: Bottom Up
    1. Problem: approximate the value of π as follows: toss darts at a 2×2 dart board centered at (0, 0). Then the ratio of the darts hitting the board in the unit circle centered at (0, 0) to all darts is π/4
    2. Step 1: write a program that generates dart tosses (actually, where they hit the board) [mc-1.py]
    3. Step 2: write a program to determine if a point in the square is in the unit circle [mc-2.py]
    4. Step 3: write a program to read in a positive integer, and reject anything else [mc-3.py]
    5. Step 4: now pull it all together [mc.py]
