Write a program that draws an octogon (8-sided polygon).
Note: Choose a name for your file that is not turtle.py. When executing the "import turtle" statement, the computer first looks in the folder where the file is saved for the turtle module and then in the libraries (and other places on the path). So, it thinks the module is itself, causing all kinds of errors. To avoid this, name your program something like "myTurtle.py" or "program2.py". - Due Date: 8 September Think CS: Chapters 2 & 4

Write a program that asks the user the number of times they plan to ride the subway or bus this week. Your program should then tell the user if it is cheaper to buy a regular fare (single ride) metro card or 7-day unlimited cards. (Note: the rates increased as of 15 March 2017).
First, compute the cost per ride for the 7-day unlimited metroCard ($31.00 divided by the number of rides) and for the regular fares with bonus. Next:
- If number of rides is 1 or 2, print out the message: You should buy a regular ticket.
- If the number of rides is 3 or more, then do the following computation:
- Single cost of ride is $2.48 (cost with bonus for buying more than $5.50).
- 7-day cost of ride is $31.00/number of rides.
Otherwise, print out the message: You should buy a 7-day ticket.
Here's a sample run of the program:
How many rides? 2 You should buy a regular ticket.
And another run of the program:
How many rides? 30 You should buy a 7-day ticket.

Fill in the missing function, monthString(), in the program, months.py. The function should take number between 1 and 12 as a parameter and returns the corresponding month as a string. For example, if the parameter is 1, your function should return "January". If the parameter is 2, your function should return out "February", etc.
Note: The grading scripts are expecting that your function is called monthString(). You need to use that name, since instead of running the entire program, the scripts are "unit testing" the function-- that is, calling that function, in isolation, with differrent inputs to verify that it performs correctly.
Hint: See notes from Lecture 7 and Lab 8.
- Due Date: 8 November Reading: UMd Logical Gates Overview

Write a program that asks the user for a CSV of collision data (see note below about obtaining reported collisions from NYC OpenData). Your program should then list the top three contributing factors for the primary vehichle of collisions ("CONTRIBUTING FACTOR VEHICLE 1") in the file.
A sample run:
Enter CSV file name: collisionsNewYears2016.csv Top three contributing factors for collisions: Driver Inattention/Distraction 136 Unspecified 119 Following Too Closely 37 Name: CONTRIBUTING FACTOR VEHICLE 1, dtype: int64
This assignment uses collision data collected and made publicly by New York City Open Data, and can be found at:
https://data.cityofnewyork.us/Public-Safety/NYPD-Motor-Vehicle-Collisions/h9gi-nx95.
Since the files are quite large, use the "Filter" option and choose your birthday in 2016 and "Export" (in CSV format) all collisions for that day. We will use this data set for future programs, so, instead of downloading the test files multiple times, save a copy for future use.Hint: See Lab 8 for accessing and analyzing structured data.

Using folium (see Lab 9), write a program that asks the user for the name of a CSV file, name of the output file, and creates a map with markers for all the traffic collisions from the input file.
A sample run:
Enter CSV file name: collisionsThHunterBday.csv Enter output file: thMap.html
which would produce the html file:
(The demo above is for October 18, 2016 using the time the collision occurred ("TIME") to label each marker and changed the underlying map with the option: tiles="Cartodb Positron" when creating the map.)
This assignment uses collision data collected and made publicly by New York City Open Data. See Programming Problem #39 for details on this data set. When creating datasets to test your program, you will need to filter for both date (to keep the files from being huge) and that there's a location entered. The former is explained above; to check the latter, add the additional filter condition of "LONGITUDE is not blank".
Hint: For this data set, the names of the columns are "LATITUDE" and "LONGITUDE" (unlike the previous map problem, where the data was stored with "Latitude" and "Longitude").
- Due Date: 15 November Reading: Think CS Chapter 6 and Chapter 7
Write a function, computeFare(), that takes as two parameters: the zone and the ticket type, and returns the Copenhagen Transit fare.
- If the zone is 2 or smaller and the ticket type is "adult", the fare is 23.
- If the zone is 2 or smaller and the ticket type is "child", the fare is 11.5.
- If the zone is 3 and the ticket type is "adult", the fare is 34.5.
- If the zone is 3 or 4 and the ticket type is "child", the fare is 23.
- If the zone is 4 and the ticket type is "adult", the fare is 46.
- If the zone is greater than 4, return a negative number (since your calculator does not handle inputs that high).
A template program, copenhagenTransit.py, is available on the CSci 127 repo on github. The grading script does not run the whole program, but instead tests your function separately ('unit tests') to determine correctness. As such, the name of the function must match exactly (else, the scripts cannot find it).
A sample run:
Enter the number of zones: 3 Enter the ticket type (adult/child): Adult The fare is 34.5
And another:
Enter the number of zones: 2 Enter the ticket type (adult/child): child The fare is 11.5

Fill in the following functions in a program that maps GIS data from NYC OpenData CSV files and marks the current location and closest point:
- getData() that asks the user for the name of the CSV and returns a dataframe of the contents.
- getColumnNames() that asks the user for the exact name of the columns that contains the latitude and longitude and returns those values as a tuple. Since the NYC OpenData files use different names for the columns in different datasets (such as "Lat", "Latitude", "LATITUDE" for latitude), the program asks for the name of the column as well as the name of the data file.
- getLocale() asks the user for latitude and longitude of the user's current location and returns those floating points numbers.
- computeDist() that computes the squared distance
between two points (x1,y1) and (x2,y2):
(x1-x2)2 + (y1-y2)2

Write a C++ program that asks the user for a whole number between -31 and 31 and prints out the number in "two's complement" notation, using the following algorithm:
- Ask the user for a number, n.
- If the number is negative, print a 1 and let x = 32 + n.
- If the number is positive, print a 0 and let x = n.
- Let b = 16.
- While b > 0.5:
- If x >= b then print 1, otherwise print 0
- Let x be the remainder of dividing x by b.
- Let b be b/2.
- Print a new line ('\n').
A sample run:
Enter a number: 8 001000
