How do you convert a stringed dictionary to a Python dictionary? [duplicate]

Question

I have the following string which is a Python dictionary stringified:

some_string = '{123: False, 456: True, 789: False}'

How do I get the Python dictionary out of the above string?

Answer 1

Use ast.literal_eval:

Safely evaluate an expression node or a string containing a Python expression. The string or node provided may only consist of the following Python literal structures: strings, numbers, tuples, lists, dicts, booleans, and None.

This can be used for safely evaluating strings containing Python expressions from untrusted sources without the need to parse the values oneself.

Example:

>>> some_string = '{123: False, 456: True, 789: False}'
>>> import ast
>>> ast.literal_eval(some_string)
{456: True, 123: False, 789: False}
