Python中模拟switch-case语句

switch_case.py

"""Python并没有switch-case的语法，等效的用法要么是像上面一样用if-elif-else的组合，要么可以考虑字典"""

pets = ['dog', 'cat', 'droid', 'fly']
food_for_pet = {
    'dog': 'steak', 
    'cat': 'milk', 
    'droid': 'oil', 
    'fly': 'sh*t'
}

for pet in pets:
    food = food_for_pet[pet] if pet in food_for_pet else None
    print(food)
