- Assignments must be completed individually.
- Discussion is allowed (e.g. via Slack) but the submission should be made by yourself. Acknowledge your helpers/collaborators name in the submission if you discussed or got help from anyone.
- Use an individual github repository. A repository in FutureSystems will be given later.
Complete the following tasks. Place all answers in a file named HW2-$USERID.txt and submit it via IU Canvas. (Replace $USERID with your email name at IU e.g. HW2-albert.txt if your email address is email@example.com)
Example view of your submission:

Sign up github.com with your SSH key. Provide your github.com user name in your submission.
Create a ‘I590-Projects-BigData-Software’ repository on your account. Create ‘hw2’ branch. Provide a clone URL of ‘hw2’ branch in your submission.
This is a question for you to answer with appropriate git commands to satisfy the following descriptions:
Albert has some Python code files that he was developing on his local machine but he wanted to use github.com to trace changes and share his work with others. He already created a new repository named ‘BigData’ on his github account. So he made a copy of the repository on his machine and there was nothing in the repo. He added a ‘README.rst’ file to describe his repository first. To make sure his description looks okay he pushed his update to github and opened a webpage to check. When he get access to his repository on github.com via a web browser, he found that Contact Info was missing so he added the info in the README.rst file online using a web browser and his description showed with the new Contact Info. He returned to his local repository and updated his repository because he wanted to sync the changes that he made on github.com. His next task was adding new_feature.py and bug.py in a separate branch, not in master because he thought these two files are still in progress with different purposes. He simply created ‘next’ and ‘error’ branches in his current repository and added the two files accordingly. his all tasks are applied to github.com.
git commands that Albert used in his work above in your submission.
- Write a python program called fizzbuzz.py that accepts an integer n from the command line. Pass this integer to a function called fizzbuzz. The fizzbuzz function should then iterate from 1 to n. If the ith number is a multiple of two, print “fizz”, if a multiple of three print “buzz”, if a multiple of both print “fizzbuzz”, else print the value.
- Create a ‘hw2’ branch on your github repository ‘I590-Projects-BigData-Software’ and add fizzbuzz.py to the branch. Provide a clone URL for the branch in your submission.
