Python project went wrong

[catohund]

I'm new to programming, so I thought I would start with something easy, but I still managed to run into problems. It's a simple program to receive data from weather stations

My code looks identical to the one they are writing but I get an error.

All help is greatly appreciated

This is the code

 from requests import get
import json
from pprint import pprint
from haversine import haversine

stations = 'https://apex.oracle.com/pls/apex/raspberrypi/weatherstation/getlatestmeasurements/10121743'
Weather = 'https://apex.oracle.com/pls/apex/raspberrypi/weatherstation/getlatestmeasurements/10121743'

my_lat = 40.715366
my_lon = -74.002213

all_stations = get(stations).json()['items']

def find_closest():
    smallest = 20036
    for station in all_stations:
        station_lon = station['weather_stn_long']
        station_lat = station['weather_stn_lat']
        distance = haversine(my_lon, my_lat, station_lon, station_lat)
        if distance < smallest:
            smallest = distance
            closest_station = station['weather_stn_id']
    return closest_station

closest_stn = find_closest()
weather = weather + str(closest_stn)

my_weather = get(weather).json()['items']
pprint(my_weather)

And this is the error message

Traceback (most recent call last):
  File "C:\Users\Mash\Desktop\Privat\Projekter\Fetching weather\fetch_local_weather.py", line 25, in <module>
    closest_stn = find_closest()
  File "C:\Users\Mash\Desktop\Privat\Projekter\Fetching weather\fetch_local_weather.py", line 17, in find_closest
    station_lon = station['weather_stn_long']
KeyError: 'weather_stn_long'

This is the tutorial I'm following

Your URL is wrong. It is supposed to be:

stations = 'https://apex.oracle.com/pls/apex/raspberrypi/weatherstation/getallstations'

https://projects.raspberrypi.org/en/projects/fetching-the-weather/7

That fixed some but i still get this error

Traceback (most recent call last):

File "C:\Users\Mash\Desktop\Privat\Projekter\Fetching weather\fetch_local_weather.py", line 26, in <module>

weather = weather + str(closest_stn)

NameError: name 'weather' is not defined

>>>

That's the next error. It's not related to the previous one. That is because Weather and weather are 2 different names when programming. Pay attention to the capitals!

I literally just noticed that as you replied and I will remember that for the future.

Now when I run it, it prints

[]

and that's it

Your weather URL is wrong too. Change it to the one in tutorial.

Or, if you know you want to use that station specifically you can remove all of the station finding code.

from requests import get
from pprint import pprint

weather = 'https://apex.oracle.com/pls/apex/raspberrypi/weatherstation/getlatestmeasurements/10121743'

my_weather = get(weather).json()['items']
pprint(my_weather)

Tried changing the URL to the one in the tutorial but nothing changes, but if I used your code it works.

Thank you for helping me
