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. for fTemp in range( 100, -31, -10 ): cTemp = ( fTemp - 32 ) * 5 / 9 print( fTemp, '-->', cTemp )
Problem: get user name and grade and display user information and grade as a bar graph.
# barGraph.py

# and grade and displays a bar-graph.

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.
