如何缩短这个冗长的if/elif函数？

def handle_condition_1():
    # 处理条件1的逻辑

def handle_condition_2():
    # 处理条件2的逻辑

def handle_condition_3():
    # 处理条件3的逻辑

# 定义条件和对应的处理逻辑的字典
condition_dict = {
    'condition1': handle_condition_1,
    'condition2': handle_condition_2,
    'condition3': handle_condition_3
}

# 根据条件从字典中获取对应的处理逻辑并执行
condition = 'condition1'
if condition in condition_dict:
    condition_dict[condition]()

def handle_condition_1():
    # 处理条件1的逻辑

def handle_condition_2():
    # 处理条件2的逻辑

def handle_condition_3():
    # 处理条件3的逻辑

# 根据条件调用对应的处理函数
condition = 'condition1'
if condition == 'condition1':
    handle_condition_1()
elif condition == 'condition2':
    handle_condition_2()
elif condition == 'condition3':
    handle_condition_3()

class ConditionStrategy:
    def execute(self):
        pass

class Condition1Strategy(ConditionStrategy):
    def execute(self):
        # 处理条件1的逻辑

class Condition2Strategy(ConditionStrategy):
    def execute(self):
        # 处理条件2的逻辑

class Condition3Strategy(ConditionStrategy):
    def execute(self):
        # 处理条件3的逻辑

# 根据条件选择对应的策略进行执行
condition = 'condition1'
if condition == 'condition1':
    strategy = Condition1Strategy()
elif condition == 'condition2':
    strategy = Condition2Strategy()
elif condition == 'condition3':
    strategy = Condition3Strategy()

strategy.execute()
