• Question in How-tos

Choose from one of several pre-defined scenarios, and set variables to the corresponding values.

This question has three variables: city, population, and percent_like_chocolate. These differ for each city.

• Question in How-tos

Choose from one of several pre-defined scenarios, and set variables to the corresponding values, defined in lists.

This question has three variables: city, population, and percent_like_chocolate. These differ for each city. We've defined a list for each variable, with the corresponding values. A variable called scenario picks a random position in the list, so the value of city, for example, is cities[scenario].
