如何才能更简洁地编写这些类似的if语句？

result = value1 if condition else value2

actions = {
    'condition1': action1,
    'condition2': action2,
    'condition3': action3,
    ...
}

result = actions.get(condition, default_action)()

def action1():
    # 执行操作1

def action2():
    # 执行操作2

def action3():
    # 执行操作3

# 根据条件调用对应的函数
if condition == 'condition1':
    action1()
elif condition == 'condition2':
    action2()
elif condition == 'condition3':
    action3()
...
