Pythonic式的方式来编写一系列非级联if语句

if condition1:
    # do something
elif condition2:
    # do something else
elif condition3:
    # do something else
else:
    # do something if none of the conditions are met

conditions = {
    condition1: action1,
    condition2: action2,
    condition3: action3
}

if condition in conditions:
    action = conditions[condition]
    action()
else:
    # do something if none of the conditions are met

def action1():
    # do something

def action2():
    # do something else

def action3():
    # do something else

conditions = {
    condition1: action1,
    condition2: action2,
    condition3: action3
}

if condition in conditions:
    action = conditions[condition]
    action()
else:
    # do something if none of the conditions are met
