如何在字典列表中查找字符串并获取其对整数值

def find_integer_value(dict_list, target_string):
    for dictionary in dict_list:
        if target_string in dictionary:
            return dictionary[target_string]
    return None

# 示例字典列表
dict_list = [
    {"apple": 1, "banana": 2, "cherry": 3},
    {"orange": 4, "grape": 5, "kiwi": 6},
    {"pear": 7, "melon": 8, "pineapple": 9}
]

# 目标字符串
target = "grape"

# 在字典列表中查找目标字符串并获取其对整数值
result = find_integer_value(dict_list, target)

if result is not None:
    print(f"The integer value of '{target}' is {result}.")
else:
    print(f"'{target}' is not found in the dictionary list.")

The integer value of 'grape' is 5.
