Answer 1

Any time you're dealing with data formatted like python objects, you could use the ast package to evaluate it. In this case, you want ast.literal_eval

import ast

with open('path/to/file.txt') as f:
    result = []
    for line in f:
        result.append(ast.literal_eval(line.strip()))

Answer 2

This looks like a list in JSON format without the preceding and trailing brackets. You could perhaps parse it by adding those in:

import json

def parse_object_list(value_str):
    return json.loads("[" + value_str + "]")

Or if it's definitely a Python thing, you could use the ast.literal_eval function , which should safely parse a Python literal:

import ast

def parse_object_list(value_str):
    return ast.literal_eval("(" + value_str + ")")

In this example I have placed the value in parentheses so that python will read correctly-formed values as-is, and lines of comma-separated data like this as a tuple.

Answer 3

This code may work based on your input.

import json
filename="jsonfile.txt"
with open(filename) as file:
    lines = file.read()
list_of_dict=json.loads('['+lines+']')

Answer 4

#an empty dictionary

dictionary = {}
with open("abc.txt") as file: 
  for line in file: 
    (key, value) = line.split()
    dictionary[int(key)] = value 
print ('\ntext file to dictionary=\n',dictionary)
