Unit Summary
This unit introduces pupils to string-handling techniques, they will explore how a string can be iterated over using a loop and sliced to create substrings. Pupils will be introduced to arrays and lists and explore the differences between the two. They will manipulate with a variety of list methods.
Lesson Summary
You will learn to create a game using two-dimensional lists.
Key Notes
- A two-dimensional list allows you to hold a list as one element.
- Data in a 2D list can be held in rows and columns.
- A 2D list can be used to create a game board.
Vocabulary To Learn
- two-dimensional: a list or array that has both columns and rows of values
- subroutine: a sequence of instructions with an identifiable name that performs a specific task
Common Mistakes To Avoid
- You cannot print a game board or table layout neatly in Python.
