append添加问题

Question

topping = []
adding = input('add your topping: ')
topping.append(adding)
print(topping)
为什么返回结果是;
add your topping: green peppers
['g', 'r', 'e', 'e', 'n', ' ', 'p', 'e', 'p', 'p', 'e', 'r', 's']
想要返回结果是['green peppers']

Answer 1

我这没问题啊

topping = []
adding = input('add your topping: ')
topping.append(adding)
print(topping)
