Big Idea 3 Lists and Filtering Algorithm

• 21 min read

Popcorn Hack #1

# original list with four movies:
movies = ["Iron Man", "The Matrix", "Interstellar", "The Dark Knight"]
print("Original list:", movies)

# adding and replacing movies
movies[1] = "The Dictator"
movies.append("Lego Batman")

print("Updated list:", movies)


Original list: ['Iron Man', 'The Matrix', 'Interstellar', 'The Dark Knight']
Updated list: ['Iron Man', 'The Dictator', 'Interstellar', 'The Dark Knight', 'Lego Batman']

Popcorn Hack #2

ages = [15, 20, 34, 16, 18, 21, 14, 19]

eligible_ages = [age for age in ages if age >= 18]

print("Eligible ages for voting:", eligible_ages)

Eligible ages for voting: [20, 34, 18, 21, 19]

Homework Hack #1

Introduction to Python Lists video:

  • Lists are a built-in data structure in Python designed for storing and accessing objects in a specific sequence.
  • Order matters in lists, making them ideal for working with ordered data.
  • Lists can be created using the list() constructor or square brackets ([]), with the latter being simpler and more common.
  • Lists can be pre-populated with values or updated later using methods like append().
  • Items in a list are accessed by their index, starting from 0 (zero-based indexing).
  • Negative indices allow access to elements from the end of the list, with -1 representing the last item.
  • Python lists can contain multiple data types (e.g., integers, strings, booleans, floats) within the same list, unlike some other programming languages that require uniform types

Introduction to List Comprehensions

  • List comprehensions provide a concise and readable way to create lists compared to traditional for loops.
  • They can simplify code significantly while maintaining clarity.
  • List comprehensions are often more readable and intuitive than using map and filter functions, making them a preferred choice for transforming or filtering data in Python.
    • example: creating a list of squares (n * n for n in nums) and filtering even numbers (n for n in nums if n % 2 == 0).
  • The video also covers dictionary comprehensions (e.g., {name: hero for name, hero in zip(names, heroes)}) and set comprehensions (e.g., {n for n in nums})
  • generator expressions are introduced as an efficient alternative to list comprehensions when working with large datasets, as they yield items lazily instead of creating a full list in memory.

Homework Hack #2

original_list = list(range(1, 31))
filtered_list = [num for num in original_list if num % 3 == 0 and num % 5 != 0]

print("Original List (1 to 30):")
print(original_list)

print("Filtered List:")
print(filtered_list)

Original List (1 to 30):
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30]
Filtered List:
[3, 6, 9, 12, 18, 21, 24, 27]

        count += 1

Review Questions:

  1. Lists in Python are ordered alterable collections used to store multiple items in a single variable. They can be modified by changing elements with indexing (my_list[0] = new_value), add items with .append() or .insert(), remove items with .remove() or .pop(), and access elements using slicing (my_list[1:3]).

  2. A filtering algorithm can be used in an online store like amazon to show only products under a certain price or within a specific category selected by the user.

  3. Analyzing the efficiency of filtering algorithms is important because it helps ensure that software runs quickly and handles large amounts of data smoothly. Efficient algorithms improve performance, reduce resource usage, and enhance the user experience, especially in data-heavy applications.
