# Global standard
SECONDS_PER_MINUTE = 60  # we learned this in grade school

# UVA standard
NBR_MWF_CLASSES = 42     # the number of MWF meetings in a semester

# CS1112 standard
MINUTES_PER_CLASS = 75   # 2:00 - 3:15 = 75 minutes

# look at the below assignment -- without context 60, 75, and 42 are
# magic numbers. they work but requires thinking and looking throughout
# the code for context
seconds_of_1112 = 60 * 75 * 42

# the below assignment makes sense in isolation. a reader can check
# above if they want to explicity know what are the values of the
# operands
seconds_of_1112 = SECONDS_PER_MINUTE * MINUTES_PER_CLASS *  NBR_MWF_CLASSES 

# An advantage to naming magic numbers is that they only need to be entered
# correctly once, so typos can be avoided.  Python will automatically make
# sure you when attempt to use the name, that it is sensible (i.e., already
# defined)

# A guideline across many programming languages is that the names for
# magic values (i.e., constants) are upper snake_case
