Part 1: Python Sequence Types: String, Lists, Tuples – Complete Guide with Examples
🧠 *Python Sequence Types: Strings, 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
