STYLE: fix violation of the DRY principle

[drveles]

What was changed

The code has been updated in accordance with the DRY principle.

Why?

It is much smaller, more concise and faster to read.

1. Closes

2. How was this tested:
   Standard tests must pass.

3. Any docs updates needed?
   No. The logic has not been changed.

Sometimes in samples we intentionally copy code as a demonstration of what a user might do if they had different code for each conditional. For example, if we really wanted to properly reuse code, we wouldn't have 4 separately named activities, we'd have one order_fruit activity that accepted a fruit type.

But I am ok with this. @dandavison - opinion?

[dandavison]

Nice cleanup @drveles. I agree -- while the activity calls are all the same it's appropriate for them to be written without repetition.

[dandavison]

A tiny thing, not related to this PR, but we should avoid using list as a variable name in Python.

[drveles]

Thank you.
I will probably correct the code according to the remark about the `list'.
