I have a .txt file with variable information and I need to read it to transform them into objects, the file is written as lists and dictionaries, is there an easy way to read them in this format?
this is an example of what is written in the txt:
[
{
"arg1":value1,
"arg2":value2
},
{
"arg1":value3,
"arg2":value4
},
]
This is valid JSON; use the json module.
import json
with open('file.txt', 'r') as infile:
data = json.load(infile)
You could interpret your input data as yaml format:
import yaml
with open('data.txt') as file:
data = yaml.safe_load(file)
[{'arg1': 'value1', 'arg2': 'value2'}, {'arg1': 'value3', 'arg2': 'value4'}]
If it's only lists and dictionaries you can use ast.literal_eval. For your example:
>>> import ast
>>> content = open('input.txt').read()
>>> lst = ast.literal_eval(content)
>>> lst
[{'arg1': 'value1', 'arg2': 'value2'}, {'arg1': 'value3', 'arg2': 'value4'}]
Note that I also quoted the values, otherwise there would be an error when evaluating the string. But if the values are numbers it will work normally.
