# Section 3.2 -- if-else statements
# if-else allows code to be run if a condition fails; this is different
# then the behavior of an "if" statement because the "if" statement does
# NOT do anything if the condition fails
#
# Syntax:
# if condition:
#     stuff (when condition succeeds)
#     more stuff
# else:
#     other stuff (when condition fails)
#     other other stuff
#

# Write the example from the board in code:
#    the example on the board says to check if "temp < 40", if yes then
#    put on coat, if not then put on sandals
# set the temperature that changes behavior
CUTOFF_TEMP=40
# get the current temperature from the user
current_temp=float(input("What is the current temperature?"))

#implement the decision structure
if current_temp < CUTOFF_TEMP:
    print("Put on your coat!")

# question was: how to implement tax?
# answer: first calculuate "gross pay" as above, then apply taxes

#           tax=pay*0.03
