As always, it's not essential that you solve or get through all of these — I'm not grading your answers on these. That said, being ''able to'' work through at least many of them is a good sign that you have mastered the concepts for the week. It is always fine to collaborate or work together on these problem sets.

1. Using <code>challenge01_traffic_getMonthToll.py</code>, write a function called getMonthToll which returns monthly toll from bgt_traffic dataset, Parameters: string of a month and a year (e.g., month = “07”, year = “2014”). Return type: integer of total toll for the month. You may use “getDayToll()” to get monthly toll.
2. Using <code>challenge02_traffic_writeYearToll.py</code>, Code challenge activity #2. Write a function called writeYearToll which saves monthly toll of a given year. Parameter: a string of year  (e.g., “2014”) (e.g., "2014“ makes “2014.csv” and save a string like:  “06/01, xxxx \n 02, xxxx\n … 12, xxxx").


3. Using <code>challenge03_wiki_theMostRevised.py</code>, write a function called theMostRevised() which receives a list of keywords and return the most highly revised keyword in Wikipedia.
