  • Learn how to use conditional statements to execute different blocks of code based on conditions.

  • Explore examples of using if-else statements to handle different scenarios.

Loops (for and while)

  • Discover how loops can repeat blocks of code multiple times.

  • Explore examples of using for and while loops to iterate over sequences and conditions.

Data Structures in Python

Python offers various data structures to organize and manage data efficiently.

Lists

Tuples

  • Understand the characteristics of tuples and how they differ from lists.

  • Explore use cases for tuples, such as representing fixed collections of data.

Dictionaries

  • Learn how to use dictionaries to store data in key-value pairs.

  • Explore methods for accessing, adding, and modifying dictionary elements.
