• Index, slice, and unpack tuples into named components.
• Use immutability to protect scientific and financial constants.
• Combine tuples with lists and dictionaries in real record structures.
• Swap values cleanly with a, b = b, a without a temporary variable.
• Use tuple methods .count(), .index(), concat +, and repeat *.
