Parsing a YAML file in Python, and accessing the data?

Question

I am new to YAML and have been searching for ways to parse a YAML file and use/access the data from the parsed YAML.

I have come across explanations on how to parse

Since PyYAML's yaml.load() function parses YAML documents to native Python data structures, you can just access items by key or index. Using the example from the question you linked:

import yaml
with open('tree.yaml', 'r') as f:
    doc = yaml.load(f)

To access branch1 text you would use:

txt = doc["treeroot"]["branch1"]
print txt
"branch1 text"

because, in your YAML document, the value of the branch1 key is under the treeroot key.
