🧠 Day 5 – Data Structures Practice Tasks

🎯 Objective

Today you explored various built-in data structures in Python — Lists, Tuples, Dictionaries, and Sets — by creating your own real-world inspired tasks and solving them with creativity. This practice is key to becoming confident in problem solving with Python.

📁 Tasks Overview

Below are the custom-built tasks that you implemented. These reflect your independent understanding of how data structures can model real-world problems effectively.

🧾 1. Lists: Top Programming Languages

Description:

  • A list of the Top 10 most advanced programming languages was created.
  • The list was updated and re-ordered manually.

Highlights:

  • Used .append() to add a new language.
  • Used direct indexing to modify list elements.
Languages = ["Rust", "Python", "TypeScript", ...]
Languages.append("JavaScript")
Languages[0] = "Python"
Languages[1] = "JavaScript"

📊 2. Dictionaries: Movie Rating System

Description:

  • Created detailed dictionaries for 4 fictional/upcoming movies.
  • Each dictionary included metadata (director, lead actors, ratings, pros, cons).
  • Implemented a selection system using input to fetch specific movie info.

Highlights:

  • Used nested dictionaries.
  • Used lists inside dictionaries for pros & cons.
  • Handled dictionary traversal using loops and conditionals.
Movie_list = {
    "saiyaara": saiyaara_2025,
    "kingdom": kingdom_2025,
    ...
}
movie = input("Enter the movie name: ")
for key, value in Movie_list[movie].items():
    if isinstance(value, list):
        for item in value:
            print(item)

🔁 3. Tuples: Car Brands & Models

Description:

  • Created a list of tuples where each tuple represents a car brand and its models.
  • Used nested loops to print each brand with its respective models.

Highlights:

  • Demonstrated how tuples can pair fixed keys (brands) with list values (models).
  • Used enumerate() and index() effectively.
car_brands = [
    ("BMW", ["X5", "X3"]),
    ("Tesla", ["Model S", "Model X"])
]

♠️ 4. Sets: Cards and Unique Numbers

Description:

  • Modeled a deck of cards using nested sets.
  • Demonstrated set uniqueness with repeated number input.

Highlights:

  • Created a dictionary of suits, each containing a set of values.
  • Used sets to automatically remove repeated numbers.
cards = {
    "Hearts": {"Ace", "2", ..., "King"},
    ...
}
Numbers = {1, 2, 3, ..., 50, 1, 2, 3, ..., 50}

✅ What You Practiced

  • ✔️ Data modeling with real-world context
  • ✔️ Using correct methods for each data structure
  • ✔️ Input/output control
  • ✔️ Loops, conditionals, and formatting

🏁 Well Done!

You did this day completely by yourself — that's a huge milestone. Keep challenging yourself with creative tasks like these to sharpen your logic and Python fluency.
