关于python：有没有办法在文本周围插入花括号，使其成为字符串格式的字典？


Is there a way to insert curly braces around text to make it a dictionary in string format?

在我的python程序中，我有一个添加到文本文件中的键和值的列表，我需要能够提取这个字符串列表并将其转换为字典。

例如：

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
    counter = 0
    add = str(counter)
    counterDict = UserID +":" + add +","
    counter = counter + 1

#This should make counterDict look like:""Smi39119": 0,"Joh38719": 1," etc.

    f = open("Dictionaries.txt","a")
    f.write(counterDict)
    f.close()

#Then I would like to be able to open the file and turn that string into a dictionary

    f = open("Dictionaries.txt","r")
    string = f.read()

#This way 'string' should still be a string, but look like this:"{"Smi39119": 0,"Joh38719": 1, }"

我不知道这是否可能，但如果可能，所有的解决方案都会非常感谢。

我猜你是想把字典保存到一个文件中，*回车*：json文件系统，您不需要将字典转换为字符串，让JSON将其转换为字符串。

10
import json

f = open("Dictionaries.json","a")
f.write(json.dumps(your_dictionary))
f.close()

# load it and use it like a dictionary

f = open("Dictionaries.json","r")
your_dictionary = json.loads(f.read())

还读写一个dict到txt文件和读回来？

干杯！
