2.13. Chapter Exercises¶
==
is an operator that checks for equality. If the value on the left side is equal
to the value on the right side, it gives True
. Otherwise it gives False
.
Insert the correct operators in place of the #
’s so each line prints True
. Don’t change any
of the numbers.
Add a set of parentheses to the expression x = 6 * 1 - 2
so that the code below prints -6 instead of 4.
Add parentheses to x = 12 * 2 - 3 + 4 * 2
so that it prints -4 instead of 29.
Complete the code on lines 3 and 5 below to print the cost of a car trip of 500 miles when the car gets 26 miles per gallon and gas costs 3.45 a gallon. It should print 66.34615384615385.
It is currently 10:00, complete the code to tell what time it is going to be in 18 hours (12-hour time, not 24-hour time). The answer should be 4 because 28 hours divided into 12 hour chunks leaves a remainder of 4 hours.
Hint: rember that **%* is the modulo or remainder operator.*
Finish the code on lines 2 and 3 in the code below to print how many hours and minutes you have been waiting when you have been waiting a total of 270 minutes. Remember that there are 60 minutes in an hour. It should print 4 and then 30.
Hint: don’t forget the difference between division and integer division.
