That's because you haven't defined pressure.
When Python tells you there is a bug in your program, it is almost
always correct.
# A small program to fetch local barometer reading from weather.com #
and convert the value from metric to imperial. # My first attempt at
Python.
#--------------------------------------------------------------------
import urllib
# next line does the fetching
urllib.urlopen("http://xoap.weather.com/weather/local/USMI0060";,
pressure)
What is pressure? It is an undefined name. Where does pressure get its
value from?
Pressure is a term for barometric pressure, and is understood by Conky,
which this program is designed to work with, and is understood by
weather.com. But the value it passes to conky is metric, and I want it to
display in imperial.
What should I do....
You're passing in the value of pressure as the 'data' parameter to
urllib.urlopen. So...what is the value of pressure? You haven't
assigned any value to it before calling urlopen. Therein lies the problem.
