Json Key_value to stdout using python

I'm new to python scripting .I'm trying to parse a json key_value to stdout. Below is my script.Help me out in fixing below error.

    pt="{'outval': 1.132805, 'max': 1.13283, 'to': 1534326908, 'bvalue': 1.13274, 'min': 1.132805, 'from': 1534326907, 'cvalue': 1.132825, 'at': 1534326907164488223, 'avalue': 1.13291, 'size': 1, 'aid': 1, 'vl': 0, 'id': 17777726}"

    print(pt["outval"])
    print(pt["to"])
    print(pt["from"])

Error :

Traceback (most recent call last): File "j.py", line 5, in <module> print(pt["outval"]) TypeError: string indices must be integers, not str

Expected output:

1.132805
1534326908
1534326907

Thanks in advance

Thanks Jon for the idea. I used ast.literal_eval to extract required key pair.Below is my updated code.

import json
import ast

pt="{'outval': 1.132805, 'max': 1.13283, 'to': 1534326908, 'bvalue': 1.13274, 'min': 1.132805, 'from': 1534326907, 'cvalue': 1.132825, 'at': 1534326907164488223, 'avalue': 1.13291, 'size': 1, 'aid': 1, 'vl': 0, 'id': 17777726}"

s=ast.literal_eval(pt)
print(s['outval'])
print(s['to'])
print(s['from'])

output :

root@lamp-1-vm:~/1# python j.py
1.132805
1534326908
1534326907
