Does it make sense to create many simple methods?

Question

Programming

How correct or incorrect it is to create many simple methods that essentially differ only in a few points, for example:

I have a class and it has a
read_from_register() method

how correct it is to create wrapper methods for easier data access, for example:

получить_статус_прибора(){
  return прочитать_из_регистра('0x00');
}

or

получить_температуру_прибора(){
  return прочитать_из_регистра('0x01')/100;
}

Will not a lot of unnecessary memory be spent or look stupid?

Or is it more correct to write something generic like:

получить_параметр_прибора(имя_параметра){
  switch(имя_параметра){
    case 'температура':
      ответ = прочитать_из_регистра('0x00');
    break;
    case 'статус':
      ответ = прочитать_из_регистра('0x01')/100;
    break;
  }
  return ответ;
}

Interesting opinion from all sides and the maintenance of the code and its "beauty", as well as in terms of saving resources.

Thanks in advance.

Answer 1

Many concrete wrapper methods are better than a big switch. maybe the calling code almost always knows what it is reading. Excessive memory will not be spent much - very often the compiler can inline this.
The option with a switch is both less efficient and less beautiful.

Answer 2

Are the classes not suitable?

прочитать_из_регистра = print

class Device (object):
    def __init(self):
        pass
    
    def temperature(self):
        return прочитать_из_регистра('0x00')
    
    def status(self):
        return прочитать_из_регистра('0x01')


device = Device()
device.status()
device.temperature()

0x01
0x00
