将文件中的行添加为字典以列出Python

Question

Im trying to import a file which contains lines like this:

 { "dictitem" : 1, "anotherdictitem" : 2 }

I want to import them in to a list of dictionaries like this:

[{ "dictitem" : "henry", "anotherdictitem" : 2 },{ "dictitem" : "peter", "anotherdictitem" : 4 },{ "dictitem" : "anna", "anotherdictitem" : 6 }]

I tried this: tweetlist = open("sample.out").readlines()

But then they get appended as a string. Does anyone have an idea? Thanks!

Answer 1

You need to decode each line using json . Example:

import json

list = []
with open("data.txt", 'r') as file:
    for line in file:
        dict = json.loads(line)
        list.append(dict)

print(list)

Answer 2

You can use the AST library's literal_eval function on each line by using a list comprehension like this:

import ast
tweetlist = [ast.literal_eval(x) for x in open("sample.out").readlines()]

ast.literal_eval is a safer version of the eval function that doesn't execute functions.
