如何将字符串添加到字典的所有整数值

my_dict = {1: "apple", 2: "banana", 3: "cherry"}

def add_string_to_dict_values(string, dictionary):
    for key in dictionary:
        dictionary[key] += string

add_string_to_dict_values(" fruit", my_dict)

print(my_dict)

{1: 'apple fruit', 2: 'banana fruit', 3: 'cherry fruit'}
