Task – Investigate

What’s an Investigate task?

In investigate tasks you are given some example code. Underneath it are questions to make sure that you understand how the code works. Use comments to answer the investigate questions on the example code.

List Operations – Reference Table

Output item	Outputs a single item from the array.	print(arrayName[itemIndex]) print(sweets[3])
Edit item	Changes or replaces an item in an array.	arrayName[itemIndex] = New data sweets[1] = “Haribo”
Add an item	Puts a new item onto the end of the array	arrayName.append(new data) sweets.append(“Galaxy”)
Remove an item	Removes an item from the array	arrayName.pop(itemIndex) sweets.pop(2)
Output all items	Outputs every item in the array one by one using a loop.	for i in range(0, len(arrayName)): print(arrayName[i]) for i in range(0, len(sweets)): print(arrayName[i]) OR #This is a nice built in Python shortcut, but you need to know how to do the for loop version for the exam. print(sweets)

Help! My code doesn’t work

Make sure that you check for the following things:

The list name is identical everywhere it is used (capitals matter)
List index is surrounded by square brackets
List indexing starts at zero – are you counting properly?
