Hi,
I want to load the following yaml content:
Yellow: 1
Blue: 2
Red: 3
And build two arrays: one for keys, that must be in this order:
['Yellow', 'Blue', 'Red'] and another for values:
[1, 2, 3]
How can I do that?
Thanks

As far as I can tell, you can't. This is because the notation
key: value
in YAML represents a hash, which is sorted in an arbitrary order. If you want
to keep the order, the simplest way is to replace the YAML hash with a nested
list:
- [Yellow, 1]
- [Blue, 2]
- [Red, 3]
I hope this helps
