Study Notes
Python Data Structures - Tuples
- Tuples are ordered, immutable sequences of items
- Items can be any data type (e.g., numbers, strings, other tuples)
- Defined using parentheses
()and commas to separate items - Creating a tuple with one element requires a comma after the element. e.g.
(1,) - Tuples are immutable; you cannot change elements after creation. Attempting to modify a tuple will result in a
TypeError - Accessed using index positions (starting at 0)
- Similar to strings, you can iterate over, slice or index them
Python Data Structures - Lists
- Lists are ordered, mutable sequences of items
- Items can be any data type (e.g., numbers, strings, other lists)
- Defined using square brackets
[]and commas to separate items - Lists are mutable, meaning you can change elements after they are created
- Accessed using index positions (starting at 0)
- Can be iterated over, sliced, and indexed in a similar way to tuples
Python Data Structures - Sets
- Sets are unordered collections of unique elements
- Items can be any hashable data type (numbers, strings, tuples, but not lists)
- Defined using curly braces
{}and commas to separate items - Sets do not allow duplicate elements.
- Elements aren't accessible by index; you must iterate over them
- Sets support various operations like union, intersection, difference, etc.
Python Data Structures - Dictionaries
- Dictionaries are unordered collections of key-value pairs
- Each key is unique and immutable (like keys in a real-world dictionary)
- Values can be any type
- Defined using curly braces
{}with key-value pairs separated by colons and items separated by commas - Accessed using keys, rather than indexes
- Mutability: Keys and values in a dictionary are mutable, allowing you to change the values associated with keys
