Pretty print Python dictionary from command line

Question

I can pretty print JSON from the command line easily:

$ echo '{"hello": "world"}' |python -mjson.tool
{
    "hello": "world"
}

However it doesn't work for Python dictionaries (obviously):

$ echo "{'hello': None}" |python -mjson.tool
Expecting property name: line 1 column 1 (char 1)

Is there some built-in class I can use similar to json.tool to pretty print Python data structures?

This project is a nice solution to this problem:

https://github.com/wolever/pprintpp

From the README:

$ pip install pprintpp

$ echo "{'hello': 'world'}" | pypprint
{'hello': 'world'}
