TT1 Data Structures

• Collection is a data structure that holds more than one value (Ex: list)
• List is a class, has methods
• How to access methods? use "." (Ex: .append)
• Ex: infodb
• Initializing DB as empty list, appending dictionary to list
• Can access entries with 'get' or index value
• For loop: doesn't require counter
• While loop: requires counter
• Recursive loop: requires counter
• NOTE: need to use exit condition to make sure recursive loop eventually terminates
• Use tester for all backend code
