1.6. Try It Yourself

Today, we are going to write our first program in Python! Let's start with something simple: printing your name. Can anyone tell me how we can do that?

I think we can use the print() function!

Excellent! The print() function is used to display information on the screen. Now, who can give me an example of how to print their name?

I would write: print('My name is John.').

Great job! Remember, the text inside the quotes is called a string. Let's all try this out together! I'll give you a moment to run this code.

I did it! Now it shows 'My name is John' on the screen!

Awesome! Now, can anyone tell me why the print() function is useful?

It helps us see what our code is doing!

Exactly! To summarize: today we learned how to use the print() function to display our name. Nice work, everyone!

Now that we've printed our names, let’s move on to printing a number. What command would we use?

We will still use the print() function!

Correct! But instead of a string, we can print a number directly. For example, we can write: print(100). Who can tell me what this does?

It should display the number 100 on the screen!

Yes! Let's try it out together. I want everyone to write print(100) and run it.

Mine worked! It printed 100!

Excellent! Printing numbers opens the door to mathematical operations. Can anyone think of a reason why printing numbers might be useful in programming?

We can use it for calculations, or to show results of other operations!

Exactly! You are all doing wonderfully. Today we've learned how to print not just strings, but also numeric values. Let’s keep going!

Finally, let’s combine what we’ve learned so far and try printing a_math_result. We can do this with another print() command. Who can guess what we might print this time?

Maybe we can do some math, like print(5 + 7)?

Absolutely right! The expression 5 + 7 is evaluated, and print will display the result. Let's try typing that out.

I see it! It printed 12!

Wonderful! This shows how Python can handle arithmetic. Why do you think it is important to understand how to use these simple math operations in our code?

Because we might need to calculate things in our programs!

Exactly! Whether for games, data analysis, or more, math is everywhere in programming. Let’s recap what we’ve learned today. We printed our names, we printed a number, and finally, we printed the result of a simple calculation. Great job, everyone!
