Hello! You can find all of these 'symbols' as predefined strings in string module.

import string

print(string.puntualtion)
print(string.ascii_letters)
print(string.digits)

Output:
'!"#$%&\'()*+,-./:;<=>?@[\\]^_`{|}~'
'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'
'0123456789'

These are from the first 128 or as they are called ascii symbols. The extended ascii includes even more. There are utf-8, utf-16, utf-32 and bunch of regional country codes. So, for simple tasks as your ascii works but if you have to expand the boundaries of a concept to include the rest it becomes a "bit" messy.

The tests we always made when there was no utf,
was as follows:

all special characters -- if hex value of character (ASCII) is one of the following,

• < 30 special
  
• 3A - 40 special
  
• 5B - 60 special
  
• > 7A special
  

if character value hex was between 30 and 7E hex, it was printable
