Python：将 list 写入一个 txt 文件四种方法

一个数据list of dict如下

a = [
    {"Jodie1": "123"},
    {"Jodie2": "456"},
    {"Jodie3": "789"},
    ]

写入到本地一个txt文件，内容格式如下：

Jodie1,123
Jodie2,456
Jodie3,789 """

import re
import json

a = [
    {"Jodie1": "123"},
    {"Jodie2": "456"},
    {"Jodie3": "789"},
    ]

方法一

with open("1.txt", "w") as f:
    for i in range(len(a)):
        for key, values in a[i].items():
            print(key+","+values+"")
            f.write(key+","+values+"")

方法二

file = open("2.txt", "w")
for i in range(len(a)):
    s = str(a[i]).replace("{", "").replace("}", "").replace(""", "").replace(":", ",") + "
"
    file.write(s)
file.close()

方法三

file3 = open("3.txt", "w")
for i in range(len(a)):
    s = (re.sub(r"["{ },]*", "", str(a[i])) + "
").replace(":", ",")
    file3.write(s)
file3.close()

方法四

with open("4.txt", "w") as f:
    for i in range(len(a)):
        s = (re.sub(r"["{ },]*", "", str(a[i])) + "
").replace(":", ",")
        f.write(s)
