有没有办法简化这个if/else代码块？

result = "Yes" if condition else "No"

actions = {
    "condition1": action1,
    "condition2": action2,
    "condition3": action3,
}
result = actions.get(condition, default_action)()

def action1():
    # do something

def action2():
    # do something

def action3():
    # do something

actions = {
    "condition1": action1,
    "condition2": action2,
    "condition3": action3,
}
result = actions.get(condition, default_action)()

class Strategy:
    def execute(self):
        pass

class Strategy1(Strategy):
    def execute(self):
        # do something

class Strategy2(Strategy):
    def execute(self):
        # do something

class Strategy3(Strategy):
    def execute(self):
        # do something

strategies = {
    "condition1": Strategy1(),
    "condition2": Strategy2(),
    "condition3": Strategy3(),
}
result = strategies.get(condition, default_strategy).execute()
