In Python, lists (list) and tuples (tuple) are similar but have important differences that affect the choice:
- List — a mutable data type. Used when you need to store a sequence of elements that you plan to modify (add, remove, change).
- Tuple — an immutable data type. Suitable for storing fixed sets of data that should not change after creation.
Example:
# List for storing tasks that can change
tasks = ['make report', 'call client']
tasks.append('send email')
# Tuple for storing coordinates of a point that do not change
point = (10, 20)
Using tuples can also improve data performance and security, as they are immutable.
