What to Focus On
- Tuple elements are enclosed in round brackets and separated by commas.
- Tuple indexing starts from 0.
- A tuple can contain integer, float, string, list, or another tuple.
- A single-element tuple must end with a comma.
- Without the comma, (20) is treated as an integer, not a tuple.
- A comma-separated sequence without parentheses is treated as a tuple by default.
- Tuples cannot be changed after creation.
- Trying to assign a new value to a tuple element raises TypeError.
- A tuple can contain a mutable element such as a list.
Common Mistakes to Avoid
A tuple can be changed after it is created, just like a list.
A single-element tuple can be written as (20).
A comma-separated sequence without parentheses is not a tuple.
