Python hex() built-in function

From the Python 3 documentation

Convert an integer number to a lowercase hexadecimal string prefixed with “0x”. If x is not a Python int object, it has to define an __index__() method that returns an integer.

Introduction

The hex() function in Python is a built-in function that converts an integer into its corresponding hexadecimal representation. The resulting string is prefixed with “0x” to indicate that it is a hexadecimal value. This function is useful when you need to work with hexadecimal numbers, which are common in low-level programming, such as when dealing with memory addresses or color codes.

Examples

hex(1)
hex(10)
hex(100)
hex(1000)

'0x1'
'0xa'
'0x64'
'0x3e8'
