Module 08
Collections Deep Dive
Learn Python collection types deeply: list, tuple, set, frozenset, dictionary, and mixed combinations.
01
Collections Deep Dive — Overview
Choose the right Python collection: list, tuple, set, frozenset, or dict. Compare order, duplicates, mutability, and indexing in one roadmap.
02
List Methods — append(), insert(), remove(), pop(), clear()
Master Python list mutation methods: append and insert at any index, remove by value, pop by index, and clear all elements in place.
03
List Methods — index(), count(), enumerate(), extend()
Search Python lists with index() and count(), iterate with enumerate(), and merge lists using extend() or the + operator.
04
List Methods — sort(), reverse(), copy(), and del
Sort and reverse Python lists in place, copy safely with copy() vs aliasing, and delete elements with the del statement.
05
Nested Lists, 2D Lists, and Matrices
Work with inner lists, multi-level indexing and slicing, matrix rows, nested loops, combining 2D lists, and shallow copy pitfalls.
06
Tuple Deep Dive — Immutable Sequences
Create Python tuples safely, avoid the single-element trap, convert from lists and strings, unpack coordinates, and know when tuples beat lists.
07
Tuple Methods — index(), count(), and sorted()
Use the only two tuple methods, understand what tuples cannot do, and sort tuple data with built-in sorted() without mutating the original.
08
Set Basics — Uniqueness, Creation, and Limitations
Create Python sets from lists and strings, remove duplicates, use membership checks, and learn why sets have no indexing.
09
Set Methods — add(), remove(), discard(), pop(), update()
Mutate Python sets safely: add elements, remove with remove() vs discard(), pop arbitrary items, merge with update(), clear, and copy.
10
Set Algebra — union(), intersection(), difference(), and more
Master Python set algebra with methods and operators: union, intersection, difference, symmetric difference, and subset relationships.
11
Frozenset — Immutable Sets and Read-Only Algebra
Create immutable sets, perform read-only set algebra, and understand when frozenset is required for dictionary keys and nested sets.
12
Dictionary Methods — get(), keys(), values(), items(), update()
Access and mutate Python dictionaries safely using get(), iterate with keys/values/items, merge with update(), and remove with pop() and popitem().
13
Nested Dictionaries and Collection Combinations
Model real-world records using nested dictionaries and combine dictionaries with lists, tuples, and sets safely.
14
Hashability Rules and Collection Conversions
Learn which Python objects can become dictionary keys or set elements, fix TypeError unhashable type, and master conversions between list, tuple, set, and dict.
15
Collections Practice — Interview Programs
Final revision covering list, tuple, set, frozenset, and dictionary with interview-style coding problems.
