In this tutorial, we will learn how to use the **div** keyword in Python. The **div** (short for “division”) is an arithmetic operator that performs integer division, which means it returns the quotient of a division as a whole number.

The **div** operator is an important and commonly used part of the Python programming language, and understanding its proper usage is essential for beginners and advanced developers alike.

### Step 1: Understanding the div operator in Python

Before we dive into the **div** operator, it is important to understand that there are two types of division in Python:

**Standard Division (operator: /):**Returns the quotient of the division, including decimals.**Integer Division (operator: //):**Also known as floor division, the result of the division will be the whole number of the quotient. Any decimals are ignored, and the result will be rounded down.

To run these operations in Python, simply use the corresponding operator between two numbers:

1 2 |
standard_division = 10 / 3 # result will be 3.3333333333333335 integer_division = 10 // 3 # result will be 3 |

As you can see, the standard division returns a float, while the integer division returns an integer result.

### Step 2: Using the divmod() function

If you want both the quotient and the remainder of a division, you can use the built-in **divmod()** function. This returns a tuple containing the quotient and the remainder of a division operation. The syntax for the function is as follows:

1 |
divmod(a, b) # a and b are the dividend and divisor, respectively |

Here is an example of how to use the **divmod()** function:

1 |
quotient, remainder = divmod(10, 3) # (3, 1) |

This returns the tuple (3, 1), where 3 is the quotient and 1 is the remainder.

### Step 3: Best practices for using the div operator

When using the division operators in Python, be mindful of the following best practices:

- Avoid dividing by zero, as it will result in a
**ZeroDivisionError**. - Be aware of the data types you are working with. The division operator returns a float, and the
**div**operator returns an integer. Make sure you are using the appropriate operator for your specific use case. - If you need both the quotient and the remainder, use the
**divmod()**function instead of performing the division and modulo operations separately. This will make your code more efficient and easier to read.

## Full Code

1 2 3 4 5 6 7 8 |
standard_division = 10 / 3 print('standard_division:', standard_division) integer_division = 10 // 3 print('integer_division:', integer_division) quotient, remainder = divmod(10, 3) print(f'(quotient, remainder): ({quotient}, {remainder})') |

## Output

standard_division: 3.3333333333333335 integer_division: 3 (quotient, remainder): (3, 1)

## Conclusion

In this tutorial, we have discussed the **div** operator in Python, which is used to perform integer division and return a whole number quotient. We also discussed the **divmod()** function, which returns both the quotient and the remainder of a division as a tuple. Understanding the **div** operator and the **divmod()** function are essential for working with division and arithmetic operations in Python efficiently. Apply these concepts and best practices in your programming to make it more efficient and concise.
