Let's study Python

Mastering the `int` class in Python is key to handling integer values with ease in your projects.

# Python Class Int Usage

In Python, the `int` class is used to create integer objects. Integers in Python can be positive or negative whole numbers with no decimal point. In this guide, we will explore how to use the `int` class in Python and some common operations that can be performed with integer objects.

## Creating Integer Objects

To create an integer object in Python, you can simply assign a whole number to a variable. For example:

“`python
x = 5
“`

In this example, we have assigned the integer value `5` to the variable `x`. Python will automatically create an integer object to represent this value.

You can also explicitly create an integer object using the `int` constructor. For example:

“`python
y = int(10)
“`

Here, we have created an integer object with the value `10` using the `int` constructor.

## Basic Operations with Integers

Once you have created integer objects, you can perform various operations on them. Some of the common operations include:

### Addition

You can add two integer objects together using the `+` operator. For example:

“`python
a = 5
b = 10
c = a + b
print(c) # Output: 15
“`

### Subtraction

You can subtract one integer object from another using the `-` operator. For example:

“`python
x = 20
y = 5
z = x – y
print(z) # Output: 15
“`

### Multiplication

You can multiply two integer objects together using the `*` operator. For example:

“`python
p = 3
q = 4
r = p * q
print(r) # Output: 12
“`

### Division

You can divide one integer object by another using the `/` operator. Division in Python always returns a float. For example:

“`python
m = 10
n = 2
o = m / n
print(o) # Output: 5.0
“`

### Floor Division

If you want to perform integer division and get an integer result (floor division), you can use the `//` operator. For example:

“`python
u = 10
v = 3
w = u // v
print(w) # Output: 3
“`

### Modulus

You can find the remainder of the division of two integers using the `%` operator. For example:

“`python
s = 10
t = 3
remainder = s % t
print(remainder) # Output: 1
“`

## Converting to Integers

Sometimes you may need to convert other data types to integers. You can do this using the `int` function. For example:

### Converting a String to an Integer

You can convert a string representing a whole number to an integer using the `int` function. For example:

“`python
num_str = “10”
num_int = int(num_str)
print(num_int) # Output: 10
“`

### Converting a Float to an Integer

You can convert a floating-point number to an integer by truncating the decimal part. For example:

“`python
float_num = 10.5
int_num = int(float_num)
print(int_num) # Output: 10
“`

## Conclusion

In this guide, we have explored the usage of the `int` class in Python. We have seen how to create integer objects, perform basic arithmetic operations, and convert other data types to integers. Understanding how to work with integers is essential for many programming tasks in Python, and the `int` class provides a convenient way to handle integer values. Practice using the `int` class in your Python projects to become more comfortable with working with integers.
