Too many 'if' statements?

Python's equivalent to a switch statement is to use a dictionary. Essentially you can store the keys like you would the cases and the values are what would be called for that particular case. Because functions are objects in Python you can store those as the dictionary values:

operation_dispatcher = {
    Operation.START: strategy_objects.StartObject,
    Operation.STOP: strategy_objects.StopObject,
}

Which can then be used as follows:

try:
    strategy = operation_dispatcher[operation] #fetch the strategy
except KeyError:
    strategy = default #this deals with the else-case (if you have one)
strategy() #call if needed

Or more concisely:

strategy = operation_dispatcher.get(operation, default)
strategy() #call if needed

This can potentially scale a lot better than having a mess of if-else statements. Note that if you don't have an else case to deal with you can just use the dictionary directly with operation_dispatcher[operation].

You could try something like this.

For instance:

def chooseStrategy(op):
    return {
        Operation.START: strategy_objects.StartObject
        Operation.STOP: strategy_objects.StopObject
    }.get(op, strategy_objects.DefaultValue)

Call it like this

strategy = chooseStrategy(operation)()

This method has the benefit of providing a default value (like a final else statement). Of course, if you only need to use this decision logic in one place in your code, you can always use strategy = dictionary.get(op, default) without the function.

You could possibly use a dictionary. Dictionaries store references, which means functions are perfectly viable to use, like so:

operationFuncs = {
    Operation.START: strategy_objects.StartObject
    Operation.STOP: strategy_objects.StopObject
    Operation.STATUS: strategy_objects.StatusObject
    (...)                  
}

It's good to have a default operation just in case, so when you run it use a try except and handle the exception (ie. the equivalent of your else clause)

try:
    strategy = operationFuncs[operation]()
except KeyError:
    strategy = strategy_objects.DefaultObject()

Alternatively use a dictionary's get method, which allows you to specify a default if the key you provide isn't found.

strategy = operationFuncs.get(operation(), DefaultObject())

Note that you don't include the parentheses when storing them in the dictionary, you just use them when calling your dictionary. Also this requires that Operation.START be hashable, but that should be the case since you described it as a class similar to an ENUM.

Starting from python 3.10

match i:
    case 1:
        print("First case")
    case 2:
        print("Second case")
    case _:
        print("Didn't match a case")
