Hello Woi Shingo! The </code> tag includes the <code>name</code> attribute to identify the data that the text area collects when the form is submitted. This is a common aspect of form elements, which are grouped together within a form tag.</p><p>When a form is submitted, the values of the form inputs are sent to the server. The <code>name</code> attribute gives a unique identity to each input, helping the server distinguish between the different pieces of data.</p><p>For example, in your current HTML code:</p><pre><code class="language-html"><form action="/html-form-submit" method="post"> <label>Write a movie plot.</label><br> <textarea name="plot" rows="3" cols="40">

Here, name="plot" tells the server that whatever text the user enters into the text area should be associated with the plot identifier once the form is submitted.

Consider this scenario:

Imagine needing to capture both a movie title and its plot in a form. You might adjust your code to look like this:

    Movie Title:

    

    Write a movie plot:

    

Here, you'd have two inputs each with a different name:

1. name="title": captures the movie title.

2. name="plot": captures the movie plot.

When this form is submitted, the server will know exactly which text is the title and which is the plot.

Hope this helps make sense of the name attribute! Let me know if you have more questions, or if there's anything else you'd like to understand better. 😊

Hello Arun! The != symbol is known as the "not equal to" operator in Python. It checks whether two values are not equal to each other. Here's how it works:

• It returns True when the values are different.

• It returns False when the values are the same.

For example, in the code you're working with:

number = 21

# This will print False because 21 is equal to 21
print(number != 21)

# This will print False because 50 is equal to 50.0
print(50 != 50.0)

# This will print True because 21 is not equal to 21.1
print(number != 21.1)

In the first two cases, both values are equal, so it prints False. In the last case, 21 is not equal to 21.1, so it prints True.

Keep practicing with these comparison operators, and you'll get the hang of them! If you have more questions, feel free to ask!

Python doesn’t care about singular/plural. languages is the list name, and language is just a variable you chose to store each item one by one, and you can name it anything like item or x. People often use language because it makes the code easier to read.

Example:

languages = ["English", "German", "French"]
for item in languages:
    print(item)

Yes, it changes the meaning a lot. line-height: 1.5; is unitless, so it means 1.5 times the font size, but line-height: 1.5px; forces the line height to be only 1.5 pixels, which is tiny and crushes the text. That’s why lessons usually use the unitless version for readable, scalable spacing.

Great question. This trips a lot of people up when they first start using Python.

The key thing to remember is that range() stops one number before the value you put in as the second argument. So if you write:

range(1, n)

Python will count like this:

1, 2, 3, ..., n-1

It never reaches n, which is why your loop feels like it’s stopping too early.

If you actually want to include n in the loop, just add 1 to the stop value:

for i in range(1, n + 1):
    total_sum += i

Now Python will count:

1, 2, 3, ..., n

and you get the full sum you expected.

If anything still feels confusing, I’m happy to walk through another example with you.

Hello Varun, really nice question.

A lot of beginners run into this when they start working with functions in C, so you’re definitely on the right track noticing it.

Here’s the simple idea:
If you write a function like this:

int getProduct(float a, float b)

C expects that function to return an int, no matter what you actually calculate inside it. So even if a * b produces a floating-point value, C will convert it to an integer when returning it. That’s why the decimal part disappears.

If you want the full, precise result, you need the function to return a floating-point type:

double getProduct(double a, double b) {
    return a * b;
}

This keeps the decimal values and avoids losing accuracy.

And one more thing students often miss:
You have to actually use the returned value, otherwise it's wasted:

double result = getProduct(3.5, 4.6);
printf("Product: %.2f\n", result);

If anything about return types still feels unclear, feel free to ask — I’m happy to help you understand it fully.

Hello Ivan, really nice question.

It’s easy to mix up the idea of a function “returning” with what \n does in a print statement. They sound similar, but they’re completely different things.

When you write:

printf("Hey\nHow are you?");

the \n does not return from the function. It doesn’t stop anything, and it doesn’t exit the print. All it does is tell the output: start a new line here. So the text comes out like this:

Hey
How are you?

The printing continues normally after the newline.
A real return is something you do with a return statement inside a function, not with \n.

If you want more examples or want to see how multiple \n behave, I’m happy to show you.

Hello Omar, really nice question.

The logic behind SELECT in SQL is actually pretty simple once you see what problem it solves. A database table is like a giant spreadsheet. Most of the time, you don’t need every single piece of information in that table — you just need certain columns or certain rows.

SELECT is how you tell the database: “Show me only the parts I care about.”

For example, if a table has ten different columns but you only want to see age and country, you can write:

SELECT age, country
FROM Customers;

Now the database gives you just those two columns instead of the whole table. It’s efficient, it’s cleaner, and it makes it easier to work with your data.

So the real logic is:
Ask for the specific data you want instead of taking everything.

If you want to dig deeper into filtering, sorting, or selecting rows, I’m happy to help you explore that next.

Hello Omar, really nice question.

Using * in SQL grabs every column in the table. It works, but it often gives you more data than you actually need. When you switch to something like:

SELECT age
FROM Customers;

you’re telling the database exactly what you want. That makes your query faster, easier to understand, and avoids pulling in extra or sensitive information by accident.

So the idea is simple:
Only ask for the columns you actually need.
It keeps the query clean and efficient.

Hello Pratik, really nice question.

charAt() is a method in Java that lets you grab a single character from a string. You just give it the position you want, and it hands you back the character at that spot.

Java starts counting from zero, so:

• the first character is at index 0

• the second is at index 1

• and so on

For example:

String text = "Hello";
char c = text.charAt(1); // 'e'

If you try an index that doesn’t exist, Java throws an error because the string doesn't go that far.

You’ll use charAt() a lot when you loop through a string and check each character, like when counting vowels.
