📚 Quick Study Guide

  • 🍎 Creating Lists: Lists are created using square brackets `[]` and can contain elements of different data types. Example: `my_list = [1, 'hello', 3.14]`
  • Adding Elements:
    • `append(element)`: Adds an element to the end of the list.
    • `insert(index, element)`: Inserts an element at a specific index.
    • `extend(iterable)`: Appends elements from an iterable (e.g., another list) to the end.
  • Removing Elements:
    • `remove(element)`: Removes the first occurrence of a specified element.
    • `pop(index)`: Removes and returns the element at a specific index (default: last element).
    • `del list[index]`: Deletes the element at the specified index.
    • `clear()`: Removes all elements from the list.
  • ✂️ Slicing Lists: Accessing a portion of a list using `list[start:end:step]`.
  • 🧮 List Comprehension: A concise way to create new lists based on existing iterables. Example: `[x*2 for x in range(5)]`
  • 🔍 Other Useful Methods:
    • `len(list)`: Returns the number of elements in the list.
    • `sort()`: Sorts the list in ascending order (in-place).
    • `reverse()`: Reverses the order of elements in the list (in-place).
    • `index(element)`: Returns the index of the first occurrence of the element.
    • `count(element)`: Returns the number of times an element appears in the list.
