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.

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!

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).

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.

Leaving an empty line in code is simply a common practice to make the code more readable.
It doesn’t affect how the code is executed at all.

When the code gets longer, we often leave empty lines to separate different parts or group related actions together—this makes it easier to read and understand.

For example:

color1 = "blue"
print(color1) 

color2 = "pink"

color1 = color2

print(color1) 
print(color2)

In this code:

• The first two lines are about creating and printing color1.

• The next group changes the value of color1 and prints both color1 and color2.

Hi there! It's perfectly normal to feel confused at the beginning, so let's clarify the differences between a variable, a comment, and a string in Python.

1. Variable: A variable is like a labeled box that holds data in your program. You give it a name to reference the data later on. For example, if you wanted to store someone's age, you might use:

age = 25

In this line, age is the variable name, and it's storing the number 25.

2. Comment: Comments are messages in the code meant for humans to read, not for the computer. They help explain what a part of the code does. Python ignores comments when running the code. You create a comment using the # symbol:

# This is a comment
print("Hello, World!")   # This prints a greeting message

Comments won't affect your code's output; they're just there to help you and others who read your code.

3. String: A string is a sequence of characters (like letters, numbers, and symbols) enclosed in quotes. Strings are like text data. You use either single (' ') or double (" ") quotes to define a string. For example, "Hello, World!" is a string:

greeting = "Hello, World!"

In this example, greeting is a variable storing the string "Hello, World!".

I hope this clears things up for you! Let me know if there's anything else that needs clarification.

A quotient is the result you get when you divide one number by another. For example:

• 10 ÷ 2 = 5 → Quotient is 5
• 15 ÷ 3 = 5 → Quotient is 5
• 20÷ 4 = 5 → Quotient is 5
• 9 ÷ 2 = 4 (with remainder 1) → Quotient is 4

The quotient is just the whole number part of the division result (ignoring the remainder, unless you're working with decimals).

Hope that clears it up! Let me know if you'd like more clarification on this.

Great question!

In Python, int stands for integer, which means a whole number — no decimal points.

For example:

• 5, 100, and -3 are all integers.

You can also use the int() function in Python to convert other types into integers:

• int(3.7) will become 3

• int("15") will become 15

This is really useful when you're working with numbers and want to make sure you're using whole numbers for calculations.

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

Great question! Strings are used everywhere in programming because they help us work with text.

For example, your name, "Ghulam," or a message like "Hello, World!" are both strings.

You'd use strings when you need to:

• Show text to the user, like showing their name or a greeting.

• Store data that consists of words, like an address or a book title.

• Manipulate text, such as searching for certain words in a sentence or combining strings together to form new sentences.

Basically, anytime you’re dealing with text-based information, strings come in handy. They're a crucial part of most programming tasks!
