# Is Int a Data Type in Python?

//

Angela Bailey

In Python, int is indeed a data type. It stands for integer and represents whole numbers without any decimal points. Integers can be positive, negative, or zero.

## Defining an Integer

To define an integer variable in Python, you simply assign a value to it using the = operator. For example:

``````
x = 10
``````

The variable x now holds the value 10, which is an integer.

## Operations on Integers

You can perform various operations on integers in Python. Some commonly used operations include:

• Subtraction (-): Subtracts one integer from another.
• Multiplication (*): Multiplies two integers.
• Division (/): Divides one integer by another and returns a float.
• Floor Division (//): Divides one integer by another and returns an integer (quotient).
• Modulus (%): Returns the remainder of the division between two integers.
• Exponentiation (**): Raises one integer to the power of another.

``````
a = 5
b = 3
result = a + b
print(result) # Output: 8
``````

In this example, we add two integers (a and b) together and store the result in the variable result. The print() function is used to display the result, which is 8.

## Conversion to Integer

Sometimes, you may need to convert other data types to integers. Python provides built-in functions for this purpose:

• int(): Converts a float or string to an integer.
• float(): Converts an integer or string to a float.
• str(): Converts an integer or float to a string.

### Conversion Examples:

``````
x = int(3.14)
y = int("5")
z = str(10)
print(x) # Output: 3
print(y) # Output: 5
print(z) # Output: "10"
``````

In these examples, we convert a float (3.14) and a string (“5”) to integers using the int() function. Similarly, we convert an integer (10) to a string using the str() function.

## Type Checking

To check if a variable holds an integer value, you can use the type() function:

``````
x = 10
if type(x) == int:
print("x is an integer.")
else:
print("x is not an integer.")
``````

This code snippet checks if the variable x is of type int using the type() function and prints the corresponding message.

In conclusion, int is a fundamental data type in Python that represents whole numbers. It allows you to perform arithmetic operations and convert other data types to integers as needed.
