Hi there! Multiplying numbers in Python is quite straightforward, and it's great that you're diving into this lesson on data types.

To perform multiplication, you'll use the asterisk symbol (*), which serves as the multiplication operator in most programming languages, including Python.

Let's update the code you're working with to perform an actual multiplication:

result = 2 * 2
print("2 * 2 =", result)

This code assigns the result of 2 * 2 to the variable result and then prints it out, showing the numerical answer to the calculation.

Output

2 * 2 = 4

You can multiply any numbers using the same approach by replacing 2 with any other numbers you want to multiply.

You'll learn more about this as you follow the course, so for now, just click the Next Lesson button and continue your journey.

Hope this helps! Let me know if you have more questions about numbers or anything else you're curious about.

That's a good question!

When you look at the output, it can be difficult to notice extra spaces. That's why it's better to check the code carefully.

For example:

print("godfrey sami")

Here, there are no extra spaces before or after the text.

But:

print(" godfrey sami ")

In this case, there are spaces before and after the text — and you can clearly see that by looking at the code.

There are other ways to check for spaces automatically, but for now, we don't want to overwhelm you.

The reason the numbers 25 and 100 aren’t inside quotes is because they are being treated as numeric values, not text (strings).

In Python, when you put a number inside quotes, it becomes a string—which is a different data type.
If you want to perform calculations like addition, subtraction, or division, you should keep numbers without quotes so Python knows they are numeric values.

In your example:

age = 25
print(age)

age = 100
print(age)

Here, age is initially assigned the numeric value of 25 and later changed to 100. That's why you see them without quotes and why they print as numbers.

Hope this helps! Let me know if you have more questions.

That's a great question!

In Python, int is actually a class, and any number you create (like 1) is an object of that class.

For example, when you write:

number = 1

Here, number is an object of the int class. You can check this using the type() function:

print(type(number))  # Output: 

This shows that int is a class, and every integer you create is an object (or instance) of that class.

Hope this helps!

Fixed values are constants that cannot be changed after they are created, and in the context of strings, they are specific sequences of characters.

For example, when you define a string with either "Python" or 'Python', that exact sequence of characters is what's stored. These strings are fixed values because if you tried to change them—say, by altering the capitalization or adding extra spaces—you would end up with something entirely different.

For instance, "python" (with lowercase 'p') or "Python " (with an extra space after the text and before ") are not the same as "Python".

Hope this helps! If you have any more questions, feel free to ask.

A string in Python is essentially a sequence of characters. It's used to represent text, and you can think of it as just another way of saying "text" in the programming world.

Whenever you want to work with text data, such as names, messages, or any kind of written content, you would use a string. Strings are enclosed in either single ('...') or double quotes ("..."), and there is no functional difference between using one or the other:

# Examples of strings
name = "Ada"          # Using double quotes
message = 'Hello!'     # Using single quotes

You will learn more about strings in the upcoming chapters. For now, I suggest you continue the course.

Great question! In Python, def is a keyword used to define a function.

A function is a block of reusable code that performs a specific task—you define it once and can use it as many times as you like.

Example:

def greet(name):
    print(f"Hello, {name}!")

In the code:

• def tells Python that you're defining a function.

• greet is the name of the function.

• (name) is a parameter the function takes.

• The indented line below it is the function body, which runs when the function is called.

To actually use the function, you'd call it like this:

greet("Alice")  # Output: Hello, Alice!

Why use functions?

• They help you avoid repeating code.

• They make your programs easier to read and maintain.

• You can break a complex task into smaller parts.

Here, greeting is a variable. When you print a variable, you get the value stored inside it as the output.
That’s why when you print greeting, you see Merry Christmas—because that's the value stored in the variable.

If you want to print the word greeting itself (not the value), you need to enclose it in quotes, like this:

print("greeting")

In this case, "greeting" is treated as a string, not a variable. So the output will simply be:

greeting

Quick reminder:

• Without quotes → Python treats it as a variable and shows its value.

• With quotes → Python treats it as plain text (a string).

Hope this clears things up! Let me know if you have any other questions.

In Python, we use the if...else statement to make decisions. For example:

age = 19

if age >= 18:
    print("The person can enter inside the club.")
else:
    print("The person cannot enter inside the club.")

We have a dedicated lesson on if...else, so you’ll learn more about it as you continue the course.
For now, I recommend just keeping the flow and moving forward step-by-step.

To initialize a string in Python, you simply need to wrap your text in either single quotes (' ') or double quotes (" "). Both methods are valid and work identically, so you can use whichever you prefer or find more readable at the moment.

Here's an example:

# Using double quotes
my_string1 = "Hello, World!"

# Using single quotes
my_string2 = 'Python is fun!'

And just for a little reminder, no matter the quotes you choose, everything inside them is considered a string, and Python treats them the same way.
