Reading YAML config file in python and using variables
<p>Say I have a yaml config file such as:</p>

<pre><code>test1:
    minVolt: -1
    maxVolt: 1
test2:
    curr: 5
    volt: 5
</code></pre>

<p>I can read the file into python using:</p>

<pre><code>import yaml

with open("config.yaml", "r") as f:
    config = yaml.load(f)
</code></pre>

<p>Then I can access the variables with </p>

<pre><code>config['test1']['minVolt']
</code></pre>

<p>Style-wise, what is the best way to use variables from the config file? I will be using the variables in multiple modules. If I simply access the variables as shown above, if something is renamed, I will need to rename every instance of the variable. </p>

<p>Just wondering what the best or common practices for using variables from a config file in different modules. </p>
