Summary<\/strong>: in this tutorial, you’ll learn how to use the Python hex() function to convert an integer number to a lowercase hexadecimal string prefixed with 0x<\/code>.<\/p>\n\n\n\n

Introduction to the Python hex() function #<\/a><\/h2>\n\n\n\n

The hex() function accepts an integer<\/a> and converts it to a lowercase hexadecimal string prefixed with 0x. <\/p>\n\n\n\n

Here’s the syntax of the hex() function:<\/p>\n\n\n

hex(x)<\/code><\/span><\/pre>\n\n\n
The following example uses the hex() function to convert x from an integer (10) to a lowercase hexadecimal string prefixed with 0x<\/code>:<\/p>\n\n\n
x = 10<\/span>\r\nresult = hex(10<\/span>)\r\nprint<\/span>(result)  # ? 0xa<\/span>\r\nprint<\/span>(type(result))  # ? <class 'str'><\/span><\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
If x is not an integer, it needs to have an __index__()<\/code> that returns an integer. For example:<\/p>\n\n\n
class MyClass:\r\n    def __init__(self, value):\r\n        self.value = value\r\n\r\n    def __index__(self):\r\n        return self.value\r\n\r\n\r\nresult = hex(MyClass(10))\r\nprint(result) # ? 0xa<\/code><\/span><\/pre>\n\n\n
Output:<\/p>\n\n\n
0xa<\/code><\/span><\/pre>\n\n\n
How it works.<\/p>\n\n\n\n
