How to use on_message using discord.py in this way?

Question

I'm making a bot using discord.py. I want the bot to get triggered if a message from any user(on the server where the bot is present) is a mixture of Integers, Characters and Strings like this e.g 122-PG-CSAI-2022

How can I do so?

I'm not sure what you think the difference is between a char and string in this case, but this code will check if it contains at least one alphabetical letter and one int:

on_message(message):
    has_number = any(char.isdigit() for char in message.content)
    has_non_number = any(char.islapha() for char in message.content)

    if has_number and has_non_number:
        # do something

edit:

on_message(message):
    splits = message.content.split("-")

    # it's not in the wanted format
    if len(splits) != 4:
        # return or something else

    cont = True

    # check if first is a number within range <1, 999>
    try:
        if int(splits[0]) <= 0 and int(splits[0] >= 1000:
            cont = False
    except ValueError:
        cont = False

    # check if second is one of the options
    if splits[1] not in ["UG", "PG", "D"]:
        cont = False

    # check if third is one of the options
    if splits[2] not in ["some", "options", "here"]:
        cont = False

    # check if fourth is a number from range <2022 ...>
    try:
        if int(splits[3]) < 2022:
            cont = False
    except ValueError:
        cont = False

    # it fits all the criteria
    if cont:
        # do stuff
