General

Tuples are immutable sequence Types that can contain any data type. Tuples are iterable, and elements within tuples can be accessed via bracket notation, using a zero-based index from the left, or -1 from the right. Other Common Sequence Operations can also be used when working with tuples.

1. Extract coordinates

• Remember: tuples allow access via index, using brackets. Indexes start from the left at zero.

2. Format coordinates

• Check class tuple for more details on tuples.
• Check class str for more details on strings.

3. Match coordinates

• What methods could be used here for for testing membership?.
• Check class tuple for more details on tuples.
• Could you re-use your convert_coordinate() function?

4. Combine matched records

• Remember that tuples support all common sequence operations.
• Could you re-use your compare_records() function here?

5. "Clean up" & make a report of all records

• Remember: tuples are immutable, but the contents can be accessed via index using bracket notation.
• Tuples don't have to use parentheses unless there is ambiguity.
• Python has multiple methods of string formatting. str.format() and f-strings are two very common ones.
• There are multiple textual formatting options available via Pythons format specification mini-language.
