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

What is the correct way to join the strings "blue" and "berry" into one word?

What must you include in your program to use the random library?

String {{}} is joining two or more strings together.

```word = "Pinecone"
print(word.upper())```

Which of the following correctly selects a random letter from the word "elephant"?

a function that counts characters in a string

a part of a string extracted using slicing

What will the following Python code output?
```word = "asparagus"
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?
```char = "G"
print(ord(char))```

Which Python function converts an ASCII value back into a character?

shifts the character forward by one in the ASCII table

What does the following Python program do?
```char = input("Enter a character: ")
print(chr(ord(char) + 1))```
