Day 3 – Getting Comfortable with Python Basics | QA Apprenticeship

Hey again 👋

Today was Day 3 of my QA apprenticeship, and things are getting more interesting as we go deeper into Python. We explored some of the core fundamentals of programming — the kind of stuff that forms the base for everything that comes later.

🔍 What We Covered

Here’s what today’s class focused on:

🔹 Variables and Identifiers

We learned what variables are, how to name them, and that they act as storage for values in a program. Also found out that you can’t use keywords as variable names.

🔹 Comments in Python

We learned to use the # symbol to write comments in Python. Comments are super helpful for understanding your code later — or for explaining it to others.

🔹 Keywords Highlighted by Color

In our code editor, keywords show up in green and blue — making it easier to distinguish between regular text and reserved words.

🔹 Python Is an Interpreter

Unlike some languages that need to be compiled, Python uses an interpreter — meaning it runs code line-by-line, which is helpful for debugging.

🔹 Data Types

We covered different data types like:

Integer

Float

String

Character

🔹 Writing a Simple Math Program

We wrote a short program to add two integers using input() and print() — and also discussed the difference between integers and other data types.

🧠 My Key Takeaways

Variables are like containers that store different types of data

Python is easy to read and write, especially with its clear structure

Comments make your code more understandable

Understanding data types is essential for writing error-free code

✨ My Reflection

Every day I’m getting more comfortable with the language. Even small things — like writing comments or knowing how Python treats numbers and strings — make me feel more confident.

Looking forward to building more complex logic in the coming days.

Thanks for reading!

Catch you tomorrow in Day 4’s update 😊
