Converting String to Python Dictionary

Question

This code returns a str as the type. Given the format of tasks, how do I convert it into a python dictionary?

import json
tasks = '''{'key1': 'val1', 'key2': None}'''
new_tasks = tasks.replace("'", "\"")
new_tasks = new_tasks.replace('None', 'null')
new_tasks = json.dumps(new_tasks)
new_tasks = json.loads(new_tasks)
print(type(new_tasks))

Note: I would prefer to not use ast.literal_eval or ast.eval.

• Barmar: Get rid of the line that calls json.dumps().
• Barmar: Why don't you want to use ast.literal_eval()? This is precisely what it's intended for.
• Barmar: Your code will do the wrong thing for {'None': 'val1'} or {'key1': 'None of us are coming'}
• Prune: Please work through the documentation and/or tutorials for the json package. You have the right idea, but you need to learn the usage idioms.

Answer 1

import json
tasks = '''{'key1': 'val1', 'key2': None}'''
new_tasks = tasks.replace("'", "\"")
new_tasks = new_tasks.replace('None', 'null')
# new_tasks = json.dumps(new_tasks)
new_tasks = json.loads(new_tasks)
print(type(new_tasks))

As Barmar said, the dumps double wraps it in quotation marks

output:

<class 'dict'>
