# Study Drills
# 1 The if statement gives a false or true boolean. If the boolean is True, the indented code will run.
# 2 The code needs to be indented to demonstrate that it is the resulting code of a true if statement... to differentiate it from seperate code that comes later in the script
# 3 If it is not indented, it is run independently of the if statement. It will be run whether the if statement is true or false
# 4 Added final if statement on lines 31-32 to try out 'not' and 'and' statements.
# 5 Different values on the original variables will trigger seperate if statements... and different print lines will be output
