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.

Programming: strings and lists

Operations cannot be performed on either numbers or strings.

Operations can be performed on both numbers and strings.

Which of the following is true about operations in Python?

What is the purpose of an if statement in Python?

Which of these is **not** a valid condition in an if statement?

executes code when the condition is False

stops the program if the condition is True

What does the else part of an if statement do?

executes a block of code repeatedly for a sequence

checks a condition and executes code if it's True
