Table of Fahrenheit to Celsius conversion

# 020518.py
# D. Thiebaut
#
# print table of temperatures
# start at 100 F down to -30 F
# in steps of 10
# using the formula: Celsius = (Farhenheit - 32 ) * 5 / 9

# print the header 
print( "Fahrenheit --> Celsius" )

# display the table of temperatures
# ranging from 100 down to -30F.

Problem: get user name and grade and display user information and grade as a bar graph.

# barGraph.py
# D. Thiebaut
# this program prompts the user for her information
# and grade and displays a bar-graph.

#First name?  Dominique
#Last name?   Thiebaut
#Id?          990123456
#Final grade? 90

We didn't have time to cover this problem, because of the snow storm... But it simply displays an 8 by 8 chessboard using hash tags.

# chessBoard.py

# displays an 8x8 chessboard, as shown below.
