Python:在包含子字符串的字典中查找(字符串)键

def find_key_in_dict(dictionary, substring):
    result = []
    for key in dictionary.keys():
        if substring in key:
            result.append(key)
    return result

my_dict = {
    "apple": 1,
    "banana": 2,
    "orange": 3,
    "pineapple": 4
}

result = find_key_in_dict(my_dict, "app")
print(result)  # 输出：['apple']
