Assignment for Day 3

Take the Public Goods Game we used. Do the following:

1. Set the number of rounds to 3

2. Add a Welcome page and add some welcome messages to it. Make it visible only on the first page (hint: look at the documentation for is_displayed)

3. Show the contributions of other players in the group (including or excluding myself) Hint:

• Path 1: You can create a list of contributions and input it into the template. Then you need to check vars_for_template in the documentation.

• Path 2: You can loop over the players in the group in the template. Check {{ for p in group.get_players }} in the documentation. This is the template version of group.get_players().
