Dear Python experts,
I never figured out when to call a method with parenthesis, when is it not?
It seems inconsistent.
For example,
If I do

numberair_pressure_9amair_temp_9amavg_wind_direction_9amavg_wind_speed_9am
max_wind_direction_9ammax_wind_speed_9amrain_accumulation_9am

The above pair of lines look odd.
You delete everything on the listbox then try to iterate
over it? Is that reall

You call anything in Python (function, method, class, etc) using
parentheses. The parentheses are what makes it a call.
When you don't use parentheses you are referencing the
callable objec

You *always* CALL a method (or function) with parentheses.
But sometimes you can grab hold of a method (or function
Another thought comes to mind...

My foggy understanding of recursion is probably the reason I can't figure
this out. When turtle draws this program there is an orange line in the
green which I would prefer not to have. I've tried all I could think of,
but can't get the orange line to go away, or maybe more accurately, not to
be dr

Python's execution model is different from C, Pascal or Fortran, but it
is quite similar to Ruby, Lua and Javascript.
