Week 2 – BALT 4363 – Python Data Manipulation

This week, I focused on Chapter 2 of the Data Toolkit, which introduced the core control structures in Python: loops and conditional statements. These tools act like the “remote control” of a program, they tell Python how to move through data, make decisions, and repeat actions automatically. Even though these concepts are fundamental, the chapter explained them in a way that connected to real-world situations and examples, especially with the car analogy for loops and the decision-based examples for conditionals. Understanding these structures is key because they form the backbone of almost every data manipulation task, whether filtering a dataset or building an interactive program.

I practiced using for loops, while loops, and if/else statements, and I learned how indentation plays a huge role in Python’s structure. The chapter emphasized that indentation isn’t optional—it’s how Python knows what belongs to a block of code. Running the examples in Google Colab helped reinforce that flow, especially when I typed code incorrectly and immediately saw how formatting affected the result. I also enjoyed the hands-on exercises, like printing numbers, checking if values were even or odd, and working with a mini guessing game that combined loops, conditionals, and user input. Trying that final exercise made everything click because it showed how these elements all work together.
