Can I have multiple message handlers called on one command?

Question

I want to contribute to a telegram bot, which has its functionality split into modules. This bot shows schedule of classes in my university. I want to add my own module that displays other events. Also I want to have minimal intervention to other modules besides mine.

Schedule for current day is shown with /today command and handler for it is already defined. I want to add my own handler that will also send user a message with my events.

The question is, can I have two different message handlers declared like this:

# module1.py
@bot.message_handler(commands=['today'])
def show_classes():
    ...

# my_module.py
@bot.message_handler(commands=['today'])
def show_events():
    ...

Will this approach work? If not, what is right way to do it?

Finally reached my PC. No, this won't work. Message handler filters are checked until first match. With such a code only test() will be invoked when /con arrives.

@bot.message_handler(commands=['con'])
def test(message: Message):
    bot.send_message(message.chat.id,"test1")

@bot.message_handler(commands=['con'])
def test2(message: Message):
    bot.send_message(message.chat.id,"test2")
