[Python-ideas] Ability to use own string types

30 Jun 2020


      This will be helpful for python linters, own data types, etc.
Example:

class SQL_String(str):
      @property
      def __chr__(self): # SQL_string.__chr__ will return string that need to be before string start
           return 's'
      def __check__(self): # This method will be called by intepreter to check if string is OK
           if not str(self).endswith(';'): # For example, we want to make that this string always needed to ends with ";"
                 raise SyntaxError('Missing ";" at the end of string')
           else:
                 return True

my_sql_string = s'SELECT * FROM information_schema.tables' # SyntaxError
my_sql_string_2 = s'SELECT * FROM information_schema.tables;' # all is ok
