# This program takes data on past and current US presidents whose list is given as a python
 +
# string where the information is listed one president per line, in Comma-Separated-Value form.
 +
# The program displays selected information from this list of presidents,
 +
# such as president number, his name, the date he took office, the date he left office, and
 +
# length of his presidency in a more readable format, i.e.:
 +
# ' 1st President: Washington, George,            took office on 30 Apr 1789 left office on 4 Mar 1797: 8-year presidency.'
 +
# For current President Obama, it prints:
 +
# '44th President: Obama, Barack,                took office on 20 Jan 2009, incumbent.'
