题目

有一个数据list of dict如下

a = [

    {"test1": ""},

    {"test2": ""},

    {"test3": ""},

]

写入到本地一个txt文件，内容格式如下：

test1,123456

test2,123456

test3,123456

解题思路

1. 打开文件
2. 循环列表，提取字典
3. 提取key，value
4. 写入文件

答案

lists = [
    {"yoyo1": ""},
    {"yoyo2": ""},
    {"yoyo3": ""},
]

with open("test.txt", "w+", encoding="utf-8") as f:
    for data in lists:
        for key, value in data.items():
            f.write(f"{key},{value}\n")
