In Python3, string.hexdigits is a pre-initialized string used as string constant. In Python, string.hexdigits will give the hexadecimal letters ‘0123456789abcdefABCDEF’.
Syntax : string.hexdigits
Parameters : Doesn’t take any parameter, since it’s not a function.
Returns : Return all hexadecimal digit letters.
Note : Make sure to import string library function inorder to use string.hexdigits
Code #1 :
# import string library function import string # Storing the value in variable result result = string.hexdigits # Printing the value print(result) |
Output :
0123456789abcdefABCDEF
Code #2 : Given code checks if the string input has only hexadecimal digit letters
# importing string library function import string # Function checks if input string # has only hexdigits or not def check(value): for letter in value: # If anything other than hexdigit # letter is present, then return # False, else return True if letter not in string.hexdigits: return False return True # Driver Code input1 = "0123456789abcdef"print(input1, "--> ", check(input1)) input2 = "abcdefABCDEF"print(input2, "--> ", check(input2)) input3 = "abcdefghGEEK"print(input3, "--> ", check(input3)) |
Output:
0123456789abcdef --> True abcdefABCDEF --> True abcdefghGEEK --> False
Applications :
The string constant hexdigits can be used in many practical applications. Let’s see a code explaining how to use digits to generate strong random passwords of given size.
# Importing random to generate # random string sequence import random # Importing string library function import string def rand_pass(size): # Takes random choices from # string.hexdigits generate_pass = ''.join([random.choice(string.hexdigits) for n in range(size)]) return generate_pass # Driver Code password = rand_pass(10) print(password) |
Output:
e497FEe2bC
