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
