I have a text file with text formatted similar to the Dictionary format of python. I want to convert this text to list of Dictionary using Python. Please help. I am pasting the same text below. If anyone can help. Please mention the python code for converion.

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()))

CodePudding user response：

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.

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 ']')

#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)
