Although students work on these labs during an 80-minute class period, it would take much longer to fully complete a lab. Each lab comes with a number of challenge problems that will take even the experiences programmer nontrivial time. Labs are collaborative and open-ended, frequently asking you to think about how or why Python makes the decisions it does.</p>
                   <p class="blurb">Each problem is chosen to reinforce a particular concept, but you are free to skip around at will. You are not expected to submit your solutions to labs, although our reference solutions will be posted afterwards. Think of labs as a chance to solidify your working knowledge of Python - after all, what better way to learn Python than to practice it?</p>
