I am completely new to dictionaries and I am not even sure if this is what
I need to use.
I have a text file that I would like to run summary stats on particular
months, years and climate indices (in this case the climate indices are
rainfall and fire area, so not actualy climate indices at all).
A text file is attached but a small sample of the file:
rainfall firearea

I have used an example from a book (a primer on scientific programming with
python) and it seems to be working (see below) but I am not sure if I have
my keys etc. are set up correctly to then begin anlaysis, and even how to
use the dictionaries in my analysis. For example how can I print out the
year with calculated the mean 'firearea' of June-July-August for that year
along with the maximum 'rainfall' for June-July-august of the same year?
Any feedback will be greatly appreaciated!
