Convert Decimal to Hexadecimal in Python

This code demonstrates how to convert decimal numbers to hexadecimal in Python using the built-in hex() function.

The hex() function takes an integer and returns a string representing the hexadecimal value with a '0x' prefix.

Examples:

• hex(255) returns '0xff'
• hex(25) returns '0x19'
• hex(0) returns '0x0'
• hex(130) returns '0x82'

This function is useful for working with base-16 representations in Python.
