How do I print specific values in a key:value list from a YAML file?

I've just switched over from bash scripting to python, an am trying to understand the language by writing some code; please excuse my python ignorance.

I'm trying to determine how to pull specific key, and values from a YAML file.

ex.

import yaml

stream = open('test.yaml', 'r')
data = yaml.load(stream)

abc = data['yaml_key']

gives me something like: 

{'1': 'a', '2': 'b', '3': 'c'}

How do I print specific key:values? I was hoping that it would act like a tuple, and I could just do something like:

abc[0]

etc. But unfortunately, when I try to print out abc[#], it just prints out abc[#], but printing out abc, gives me the key:value list.

This is probably an easy one for anyone experienced in Python, but any input would be appreciated.

Contribution belongs to Padraic for his comment, but for future reference, the correct method to loading key:values is:

abc["key_value"]

Also worth noting in his response, the following:

abc.keys() // list keys
abc.get("key_value") // get specific key value
