Treehouse Moderator 68,441 PointsHey Trenton Spears, since the breed information is deeper in side the data, you will need to parse deeper into the structure. Sometimes a problem solution does not have to be generic for all input data
, it can be very specific and work only for a very specific data form.
Try the following flow:
- set the embedded
pets
list to a variable - loop through the list, adding the breeds to your
list1
- return the
list1
Post back if you need more help. Good luck!!

Python Development Techdegree Graduate 16,969 PointsI have no idea man. I've been stuck on this for about two weeks binging tutorial videos on YouTube, Treehouse, and online forums of all sorts and I'm dead on my last three exercises. Just being totally honest I'm about ready to hang it up before my next billing cycle.

Treehouse Moderator 68,441 PointsI can try to walk you through it. Do you have a local environment set up to exercise code?

Treehouse Moderator 68,441 PointsLetβs solve it without a function first.
Copy in the example dictionary (above) and assign it to a variable:
set
pets
equal to the βpetsβ item in the dictdata
:pets = data[βpetsβ]
pets
is now a list of dictionaries. Loop throughpets
extracting the βbreedβ information from each dict:Chris Freeman
Treehouse Moderator 68,441 PointsChris Freeman
Treehouse Moderator 68,441 PointsThe final step is to put the code in a function. The code above should work under the function βsignatureβ, that is, the βdefβ line you have above.
