Exercise to practice collaborative forking workflow

We will run this exercise in groups and we number the groups
1, 2, ..., etc.


  • Learn how to fork, modify the fork, and file a pull request towards forked repo
  • Learn how to update your fork with upstream changes

Part A: Fork and clone

First fork this repository on GitHub into your namespace and then clone the fork to your computer.

Part B: Modify and commit

Then add a file where N is your group number, e.g.

This file should contain a function called tweet() which returns
a string of maximum 140 characters, for instance:

def tweet():
    return "please replace this boring sentence with something more fun"

The file automatically calls all tweet() functions defined in files (1 <= N <= 50). You do not need to edit

You can test it:

$ python

group 17 says: please replace this boring sentence with something more fun

Part C: Push your changes to the fork

Once you see your sentence correctly printed, commit and push to your fork. Don't worry
nothing gets out to Twitter but please mind that your changes will be public on
GitHub (but you can delete them later).

Part D: File a pull request

Then file a pull request towards the repository where you forked from.

Wait until we integrate all pull requests into the central repo
together on the big screen.

Part E: Update your fork

We do this part after the contributions from all groups have been integrated.

Once this is done, practice to update your forked repo with the upstream
changes and verify that you got the files created by other groups:

$ python
