Ask a Question

Question-1: Other Languages: Modify the API call in python_repos.py so it generates a chart showing the most popular projects in other languages. Try languages such as JavaScript, Ruby, C, Java, Perl, Haskell, and Go.

Question-2:. Active Discussions: Using the data from hn_submissions.py, make a bar chart showing the most active discussions currently happening on Hacker News. The height of each bar should correspond to the number of comments each submission has. The label for each bar should include the submission’s title, and each bar should act as a link to the discussion page for that submission.

Question-3: Testing python_repos.py: In python_repos.py, we printed the value of status_code to make sure the API call was successful. Write a program called test_python_repos.py, which uses unittest to assert that the value of status_code is 200. Figure out some other assertions you can make—for example, that the number of items returned is expected and…

Question 1: Gross Domestic Product: The Open Knowledge Foundation maintains a data set containing the gross domestic product (GDP) for each country in the world, which you can find at http://data.okfn.org/data/core/gdp/. Download the JSON version of this data set, and plot the GDP of each country in the world for the most recent year in the data set.

Question 2:. Choose Your Own Data: The World Bank maintains many data sets that are broken down for information on each country worldwide. Go to http:// data.worldbank.org/indicator/ and find a data set

that looks interesting. Click the data set, click the Download Data link, and choose CSV. You’ll receive three CSV files, two of which are labeled Metadata; use the third CSV file. Write a program that generates a dictionary with Pygal’s two-letter country codes as its keys and your chosen data from the file as its values. Plot the data on…

Question 1: San Francisco: Are temperatures in San Francisco more like temperatures in Sitka or temperatures in Death Valley? Generate a high-low temperature plot for San Francisco and make a comparison. (You can download weather data for almost any location from http://www.wunderground.com/history/. Enter a location and date range, scroll to the bottom of the page, and find a link labeled Comma-Delimited File. Right-click this link, and save the data as a CSV file.)

Question 2: . Sitka-Death Valley Comparison: The temperature scales on the Sitka and Death Valley graphs reflect the different ranges of the data. To accurately compare the temperature range in Sitka to that of Death Valley, you need identical scales on the y-axis. Change the settings for the y-axis on one or both of

the charts in Figures 16-5 and 16-6, and make a direct comparison between temperature ranges in Sitka and Death Valley (or any two…

Question 1:

Two D8s: Create a simulation showing what happens if you roll two eightsided dice 1000 times. Increase the number of rolls gradually until you start to see the limits of your system’s capabilities.

Question 2:

Three Dice: If you roll three D6 dice, the smallest number you can roll is 3 and the largest number is 18. Create a visualization that shows what happens when you roll three D6 dice.

Question 3:

Multiplication: When you roll two dice, you usually add the two numbers together to get the result. Create a visualization that shows what happens if you multiply these numbers instead.
