[PYTHON] How to get the current weather data and display it on the GUI while updating it automatically

0. First

If you want to see how the things you make this time work, please see here (youtube video).

1. OpenWeatherMap API settings

First, access OpenWeatherMap here. Then, when you log in, a screen like this will be displayed, so go to the API above it. Then, to get the current weather data, press Subscribe in Currbnt Weather Data. Then press Free's Get API Key. Then you will be taken to the first screen, so press API Keys. Then you can see the obtained API Key.

2. Acquisition of meteorological data

get_weather_data.py

import requests
import json
import schedule

api_key = '8c5752202e9c558f8d76310d5d96ee03'
city_name = 'Tokyo'
url = f'http://api.openweathermap.org/data/2.5/weather?q={city_name}&appid={api_key}&lang=ja'
response = requests.get(url)

def show_data():
    response = requests.get(url)
    data = json.loads(response.text)
    print(data)

#data['weather'][0]['description']

If you execute show_data (), you will get the following Json data. You can get the result in Japanese by adding lang = ja at the end of the url.

{'coord': {'lon': 139.69, 'lat': 35.69}, 'weather': [{'id': 500, 'main': 'Rain', 'description': 'light rain', 'icon': '10d'}], 'base': 'stations', 'main': {'temp': 293.2, 'feels_like': 294.56, 'temp_min': 292.15, 'temp_max': 294.26, 'pressure': 1008, 'humidity': 93}, 'visibility': 7000, 'wind': {'speed': 2.6, 'deg': 80}, 'rain': {'1h': 0.64}, 'clouds': {'all': 75}, 'dt': 1589781754, 'sys': {'type': 1, 'id': 8077, 'country': 'JP', 'sunrise': 1589744047, 'sunset': 1589794888}, 'timezone': 32400, 'id': 1850144, 'name': 'Tokyo', 'cod': 200}

3. GUI settings to display

weather.py

import requests
import json
import datetime
import tkinter as tk

class Weather:
    def __init__(self,parent):
        self.api_key = '2d3e148162f779382b38d219e60e028e'
        self.city_name = 'Tokyo'
        self.url = f"http://api.openweathermap.org/data/2.5/weather?q={self.city_name}&appid={self.api_key}&lang=ja"

        self.label = tk.Label(parent,text="weather data")
        self.label2 = tk.Label(parent,text="updated time")
        self.label.pack()
        self.label2.pack()
        self.label.after(60000,self.change_info)
        self.label2.after(60000,self.change_info)


    def show_data(self):
        response = requests.get(self.url)
        data = json.loads(response.text)
        print(data['weather'][0]['description'],datetime.datetime.now())
        return data
    
    def change_info(self):
        time = datetime.datetime.now()
        data = self.show_data()
        var = data['weather'][0]['description']
        self.label.configure(text=var)
        self.label2.configure(text=time) 
        self.label.after(60000,self.change_info)
        self.label2.after(60000,self.change_info)
        

#if __name__ == '__main__':
#    root = tk.Tk()
#    weather = Weather(root)
#    root.mainloop()

run = True
while run:
    try:
        root = tk.Tk()
        weather = Weather(root)
        root.mainloop()
    except KeyboardInterrupt:
        run = False

Again, I haven't done anything particularly difficult. Every minute, change_info () is called to get the data and update the GUI label. However, if you do it if you do not comment out when you finish it, it will end at the next update, so improvement is still needed. If you know how to get a good finish, please let me know. Please.
