Part 2: Python Sequence Types: Lists, Tuples & Ranges – Complete Guide with Examples

🧠 **Python Sequence Types: Lists, Tuples & Ranges – Complete Guide with Examples | NeuralAICodeCraft**

Lists, Tuples, and Ranges – the three fundamental sequence types in Python. But when should you use each one?

In this video, you'll master all three sequence types with practical examples.

📌 **What you'll learn:**

**LISTS (Mutable Sequences)**
▸ Creating lists ([] , list(), list comprehensions)
▸ Accessing elements (indexing, slicing)
▸ List methods (append, extend, insert, remove, pop, sort, reverse)
▸ List comprehensions (Pythonic way)
▸ Nested lists (matrices)
▸ Performance considerations

**TUPLES (Immutable Sequences)**
▸ Creating tuples ((), tuple())
▸ Why use tuples over lists
▸ Tuple unpacking
▸ Named tuples (enhanced readability)
▸ When immutability matters

**RANGES (Lazy Sequences)**
▸ Creating ranges (range(stop), range(start, stop), range(start, stop, step))
▸ Memory efficiency (lazy evaluation)
▸ Converting ranges to lists
▸ Practical uses (loops, indexing)

**SEQUENCE OPERATIONS**
▸ Common operations (len, min, max, sum, sorted)
▸ Slicing ([start:stop:step])
▸ Concatenation and repetition
▸ Membership testing (in, not in)
▸ Iteration techniques

🎯 **Practice Challenge:**
1. Create a list of squares of first 10 numbers using list comprehension
2. Create a tuple of weekdays and unpack them
3. Create a range of even numbers from 2 to 20
