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

first_three = word[0:3]
print("sp" in first_three)```

a character encoding system that assigns numbers to characters

What does the following code do?
