Spinning cursor and progress bar in console (Python)

spinning_cursor.py

"""
Create a spinning cursor or progress bar in terminal can be useful
for some scripts.

1. Use '\r' to move cursor back to the line beginning. Or use '\b'
   to erase the last character.
2. The standard out of Python is buffered, which means it will 
   collect some data written to standard out before it actually 
   writes to the terminal.
   The code snippet
   for i in range(5):
     time.sleep(1)
     print i
   will wait for 5 seconds before printing '01234' into the 
   terminal.
   Use sys.stdout.flush() to force printing to terminal.

This is awesome, thank you!
