• Task: Understand variables as containers for data. Learn about the core data types: strings (text), integers (whole numbers), floats (decimal numbers), and booleans (True/False).
• Exercise: Create a script that defines variables for your name, age, and a favorite hobby. Print them out in a sentence like “My name is [Name], I am [Age], and I enjoy [Hobby].”

Day 3: Working with Strings and Numbers

• Today’s Goal: Manipulate text and perform calculations.
• Task: Explore string methods like .upper(), .lower(), and f-strings for formatting. Learn about arithmetic operators (+, -, *, /, %, **).
• Exercise: Write a script that takes two numbers, calculates their sum, product, and division, and prints the results in a nicely formatted string.

Day 4: Introduction to Lists

• Today’s Goal: Work with ordered collections of items.
• Task: Learn about lists, Python’s versatile tool for storing sequences of data. Understand how to create a list, access items by index, and add items using .append().
• Exercise: Create a list of your top three favorite movies. Print the first movie. Then, add a fourth movie to the list and print the entire updated list.

Day 5: if, elif, and else Statements

• Today’s Goal: Add decision-making logic to your scripts.
• Task: Understand how to use conditional statements to control which blocks of code run. Learn about comparison operators (==, !=, <, >).
• Exercise: Write a program that asks for a user’s age. Based on the input, print “Child,” “Teenager,” “Adult,” or “Senior.”

Day 6: for Loops

• Today’s Goal: Learn how to iterate over sequences.
• Task: Master the for loop, one of Python’s most essential constructs. Learn how to use it with lists and the range() function.
• Exercise: Create a list of numbers. Write a for loop that iterates through the list and prints the square of each number.

Day 7: while Loops and User Input

• Today’s Goal: Repeat code based on a condition and interact with the user.
• Task: Learn how while loops work. Use the input() function to get data from the user during script execution.
• Exercise: Create a simple number guessing game. The script should pick a random number, and the user has to guess it. Use a while loop to let them keep guessing until they get it right.

• Task: Understand dictionaries for storing related information. Learn how to create, access, and modify dictionary data.
• Exercise: Create a dictionary that represents a person, with keys for “name,” “age,” and “city.” Print the person’s city. Add a new key-value pair for “email” and print the entire dictionary.

Day 10: Combining Lists and Dictionaries

• Today’s Goal: Create more complex, nested data structures.
• Task: Learn how to create lists of dictionaries, which is a very common pattern for representing structured data.
• Exercise: Create a list of dictionaries, where each dictionary represents a book with keys for “title” and “author.” Write a for loop to iterate through the list and print the details of each book.

Day 11: Tuples and Sets

• Today’s Goal: Understand other useful data structures.
• Task: Learn about tuples (immutable lists) and sets (unordered collections of unique items). Understand when you might use them.
• Exercise: Create a list with duplicate numbers. Convert it to a set to automatically remove the duplicates, then convert it back to a list and print the result.

Day 12: Working with Modules

• Today’s Goal: Learn to import and use code from Python’s standard library.
• Task: Understand the import statement. Explore useful modules like math, random, and datetime.
• Exercise: Write a script that uses the random module to simulate rolling a six-sided die and prints the result. Use the datetime module to print the current date and time.

Day 13: Introduction to File Handling

• Today’s Goal: Read data from and write data to files.
• Task: Learn how to use open() to work with text files. Understand the difference between read mode ('r') and write mode ('w').
• Exercise: Write a script that asks the user for their name and then writes “Hello, [Name]!” to a file named greeting.txt.

Day 14: Error Handling with try and except

• Today’s Goal: Write more robust code that can handle unexpected errors.
• Task: Learn how to use try...except blocks to catch errors (exceptions) like ValueError or FileNotFoundError without crashing your program.
• Exercise: Write a program that asks the user for a number and tries to calculate its reciprocal (1/number). Use a try...except block to handle the case where the user enters 0 (which would cause a ZeroDivisionError).
