Answer:

^[A-Fa-f0-9]+$

Explanation:

The hexadecimal (Base 16) can contain 0-9, A-F, a-f and any of these can be the part of the Hexadecimal base 16 code.

In python we have the re.match function, and the syntax is as below:

re.match(pattern, string, flag=0). And we can use this function to check whether the entered char variable is a regex or not. Like:

re.match(pattern,x, flag=0)
