-====== Print Status Messages ======
-**General Information**
-Printing status messages in Python scripts involves flushing the standard output buffer.
-If the buffer is not flushed, Python will decide on its own when to flush it, resulting in sporadic large amounts of output. (Not useful for command line scripts/programs)
-**Checklist**
-  * Python 2 or 3
-----
-====== Usage ======
-Using the example snippet.
-<code bash>
-chmod +x print-status-msg.py
-./print-status-msg.py
-</code>
-----
-====== The Code ======
-<code python print-status-msg.py>
-#!/usr/bin/python
-#=======================
-# Import Modules
-#=======================
-# Future print function capabilities
-from __future__ import print_function
-# sys: for stdout print buffer flush
-import sys
-# time: for sleeping
-import time
-#-- Example status message code --#
-print("Doing some work", end='')
-# Loop from 0 to 59
-for count in range(59):
-  # Print a period '.' with no newline
-  print('.', end='')
-  # Flush the stdout buffer to display it immediately to the console
-  sys.stdout.flush()
-  # sleep for 1 second
-  time.sleep(1)
-print("[COMPLETE]")
