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 use string handling techniques to find things out about a string.

Key Notes

• A string is a collection of characters.
• String handling is using techniques and built-in functions to find out information about strings.
• The len() function is used to return the length of a string.
• The index number is used to retrieve a single character from a specified position in a string.
• For loops can be used to iterate through some or all of the items in a string.

Vocabulary To Learn

• string handling: how programs manipulate text through operations like joining, searching and formatting
• index: the location of items or elements in a list, array or string
• for loop: an iterative statement that will repeat for the length of a given sequence

Common Mistakes To Avoid

• Operations in programs can only be performed on numbers.
