We saw how the daily routine of a worker resembles the Template pattern. We also mentioned two examples of how Python uses Template in its libraries. General use cases of when to use Template were also mentioned.
We concluded the chapter by implementing a banner generator, which uses a Template function to implement custom text styles.
