Python Tutorial 4.1 - Lists in Python

Welcome to the “Lists in Python” tutorial!

Overview

Lists are ordered, mutable collections that can hold items of different types.

Creating Lists

fruits = ["apple", "banana", "cherry"]
numbers = [1, 2, 3, 4]
mixed = [1, "two", 3.0, True]

Common Operations

• Indexing & Slicing:

  print(fruits[0])     # "apple"
  print(numbers[1:3])  # [2, 3]
  

• Adding Items:

  fruits.append("date")
  

• Removing Items:

  fruits.remove("banana")
  

• Inserting Items:

  fruits.insert(1, "blueberry")
  

• Length & Membership:

  len(fruits)          # 4
  "cherry" in fruits   # True
  

Key Takeaways

• Lists are versatile and mutable.
• Use indexing and slicing to access elements.
• Utilize list methods to modify the list.

Happy coding!
