Regex for hexadecimal string python

Related questions
Can a regular expression find all hexadecimal numbers? While you already received two answers that find you all hexadecimal numbers, here's the same with a direct regular expression that finds you all text that does not look like a hexadecimal number (assuming that's two letter/digits in uppercase / lowercase 0-9 and A-F range, followed by a space).
How to use regex in Python? You can use RegEx in Python after importing re module. This Python code uses regular expressions to search for the word “portal” in the given string and then prints the start and end indices of the matched word within the string. Note: Here r character (r’portal’) stands for raw, not regex.
How to convert a string to a hexadecimal in Python? This approach works with both old versions of Python (2.x) and new versions of the programming language (3.x). What we will do are: Encode the string to bytes using the desired encoding, such as encode("utf-8"). Call the binascii.hexlify() function to convert the bytes to a hexadecimal representation.
What is a hex value in Python? In Python and the world of software development, a hexadecimal value (or hex value) is a representation of a number using base-16 digits and alphabets. It consists of digits 0-9 and letters A-F. The prefix 0x is optional and sometimes used to indicate that a value is hexadecimal, but it is not required.
