Python Tkinter example

This example demonstrates Python Tkinter GUI example. The code fetches weather information from URL, based on the location that is entered. You can get your API key from Openweathermap.
Note: Make sure you included a background image in the path. In this case mine is called sky.jpg.

import tkinter as tk
from tkinter import font
import PIL.Image
import PIL.ImageTk
import requests

API_KEY = 'INSERT API KEY' #TODO insert API key from Openweathermap.com

#functions
def test_function(entry):
    print("button clicked", entry)

def format_response(weather):
    try:
        name = weather['name']
        description = weather['weather'][0]['description']
        temperature = weather['main']['temp']
        final_str = 'City: %s \nConditions: %s \nTemperature (F): %s' % (name, description, temperature)
    except:
        final_str = 'There was a problem retrieving that information.'

    return final_str




def get_weather(city):
    weather_key = API_KEY
    url = 'https://api.openweathermap.org/data/2.5/weather'
    params = {'APPID': weather_key, 'q': city, 'units': 'imperial'}
    response = requests.get(url, params)
    weather = response.json()
    format_response(weather)

    label['text'] = format_response(weather)
