Python分解了一个超长的IF语句

age = 25

if age < 0:
    print("Invalid age!")
elif age < 18:
    print("You are a minor.")
elif age < 65:
    print("You are an adult.")
else:
    print("You are a senior citizen.")

def get_age_message(age):
    if age < 0:
        return "Invalid age!"
    elif age < 18:
        return "You are a minor."
    elif age < 65:
        return "You are an adult."
    else:
        return "You are a senior citizen."

age = 25
print(get_age_message(age))

def minor():
    return "You are a minor."

def adult():
    return "You are an adult."

def senior():
    return "You are a senior citizen."

age_messages = {
    age < 18: minor,
    age < 65: adult
}

message_function = age_messages.get(True, senior)
print(message_function())
