Python Learnings #2 - handling indices from YAML

I was seeing this: -

TypeError: string indices must be integers

whilst processing a list of data in Python, where said data was being read from a YAML file.

It took me a while to work out the problem/solution.

Long story very short, lists in YAML are different to key/value pairs in that lists do NOT have a key, but instead have an index.

Therefore, the YAML needs to look like: -

number:
   - 1
   - 2
   - 3

or: -

name:
   - Lisa
   - Marge
   - Bart
   - Homer
