Python 03: Python Variables and Math

We're going to dive into two fundamental concepts in Python: Math operations and Variables.

Python 03: Python Variables and Math

After exploring the Python print statement yesterday, today we're going to dive into two fundamental concepts in Python: Math operations and Variables.

Understanding Python Math Operations

Python makes math easy and intuitive. You can add (+), subtract (-), multiply (*), and divide (/) just as you would on a calculator. Let's try it:

  1. Open your Terminal (Mac) or Command Prompt (Windows).
  2. Start the Python interpreter by typing python.
  3. Now, let's do some basic math. Type print(2 + 3) and press Enter.
  4. You should see 5 as the output. That's Python doing math!

Variables: Your Personal Data Store

Variables in Python are like containers where you can store data. They're incredibly useful for handling and manipulating this data in your programs. Here's how you use them:

  1. In the Python interpreter, type x = 5 and press Enter. You've just created a variable named x and stored the number 5 in it.
  2. Now, type print(x) and press Enter. You should see 5 displayed. That's the value of your variable!

Combining Math and Variables

Variables aren't just for storing single numbers. You can perform operations on them too. Try this:

  1. Type y = 3 and press Enter to create another variable.
  2. Now, let's add x and y. Type print(x + y) and press Enter.
  3. The output will be 8, the sum of x and y.

Why Math and Variables Matter

  • Math operations are essential for calculations, data processing, and even for logic in programming.
  • Variables allow you to store and manipulate data efficiently, making your code dynamic and flexible.
