Hello, and thanks for reaching out!

You've bumped up against an important Python concept here! :) I'm not sure if 
this was intentional, but in your provided code you specified your extents as a 
"set" (docs: 
https://docs.python.org/3.10/library/stdtypes.html#set-types-set-frozenset) 
using the curly braces instead of parens or square brackets. In Python, a set 
is an unordered collection of data. Under the hood, Cartopy needs to know the 
specific order of your boundaries in `set_extent`, and so you need to specify 
them as a list (square brackets) or tuple (parentheses) for it to appropriately 
"unpack" your extents. If I change this syntax, your code runs fine on my 
machine! Hope this helps, and don't hesitate to follow up if needed. Thanks!


All the best,

Drew
