Python string hexdigits explanation with example

Python string hexdigits explanation with example:

Python string hexdigits is a string constant that contains all hexadecimal characters. It includes all these characters: ‘0, 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, f, A, B, C, D, E, F’.

This is a constant defined in python string. To access this value, we need to import string library by using import string. We can then access this constant: string.hexdigits.

Definition:

string.hexdigits

It returns a string that includes all hexadecimal characters.

Example program:

Let’s take a look at the below program:

import string

print(string.hexdigits)

If you run this program, it will print the below output:

0123456789abcdefABCDEF

As you can see here, it prints all hexadecimal characters in a string.

Python program to check if a string has only hexadecimal characters:

Let’s write a program to check if all characters in a string includes all hexadecimal characters. We can use string.hexdigits for that. Below is the complete program:

import string


def check_hexa(given_str):
    for ch in given_str:
        if ch not in string.hexdigits:
            return False
    return True


input_str = input('Enter a string: ')

if(check_hexa(input_str)):
    print('It includes all hexadecimal characters')
else:
    print('It doesnt include all hexadecimal characters')

Here,

check_hexa method is used to check if a string includes all hexadecimal characters. It returns True if all characters are hexadecimal, else it returns False.
It is taking one string as input from the user and storing that value in input_str.
It then uses check_hexa method to check if it includes all hexadecimal characters or not. Based on the return value, it prints one string to the user.
