Python code weather Led sign

[n3vo]

I did read through the summary part but was using it incorrectly, I was using it as forecast.summary() to no avail, that explains why. I tried your code and still get error ascii codec cant decode byte 0xff in position 0: ordinal not in range(128)

Is this to do with using python 3.4 vs 2.7?

[buran]

which version do you use? python3 should not have problem with unicode chars, so btter use python3, else you need to decode it (supply codec info)
by the way, I don't see what this char could be, given the summary string...

[buran]

Could you post the full Traceback? At the moment for your location forecast.currently().summary is simply "Clear', so I guess it's not the problem, but some other line where you try to print temperatute with degree sign like daily().summary

import forecastio

def main():

   api_key = "YOUR API KEY"

   lat = -31.967819
   lng = 115.87718
   #time = datetime.datetime(2017, 06, 05, 6, 0, 0)

   forecast = forecastio.load_forecast(api_key, lat, lng) #, time=time)

   #mysign = MiniSign(devicetype='sign')

   print "===========Currently Data========="
   current_weather = forecast.currently()
   print current_weather.summary

It says I am using 3.4.2

Here is the full error code from terminal

no, as you can see from the Traceback you are running it via python2.
please, post YOUR actual code

[sparkz_alot]

Make the very first line in your script:

#! /usr/bin/env python3

or call your file using

python3 -m ./filename

Linux will typically run Python v 2 by default.

[buran]

in addition to sparkz_alot's advice - make sure all required external packages (in your case - forecastio and pyledsign) are installed for the correct python version

Thank you guys so much! using sudo python3 in the command worked, I did run into the issue you talked about, Buran. I pip3 installed both applications which fixed that, I also had to add () to parts of the code to make it work in 3, which it does now! code is posted below., (which is all yours Buran, thanks very much again) I had one last question, would it be hard to implement two line text on this sign? Here is documentation on it using the same sign I have, with git info in there as well. https://medium.com/@mikemetral/a-homemad...75c73a5339

again, thank you so much for your help! I know my understanding is frustrating, just trying to learn a little bit about how this works!

you are using different package for the sign - pyledsign and he is using his own (I think) wrapper around Rubi code.

by the way in PyPi there is yet another package - https://pypi.python.org/pypi/pyLEDSign/2.0.2. I assume you installed yours from the git repo, right?

I don't see any example in your package doc that explicitly show two-line msg. I would try to send a msg with new line, i.e. '\n' in it just to see if it will yield two lines.

I did install that package! thanks. That code for pyledsign and his own is in ruby, but that isn't the link I was refering to, I think the link maybe isn't posted in the document, my apologies. here is what I am refering to, the code was all ported from ruby to python.

https://github.com/metral/led_sign
https://github.com/metral/led_sign/blob/master/test.py

I have run the test.py (second link) on my sign and it does run fine with two lines, but I was wondering if I could implement that code with the weather you have helped me with, or is that not possible. 

Thanks!
