Map of the number of people infected with the new coronavirus by prefecture https://gis.jag-japan.com/covid19jp/

I have created a site called, but I am not so enthusiastic, so I decided to create a BOT that displays the breakdown of the number of infected people.

The data of the number of infected people was put in the json file on the same site, so I will use that.

https://services6.arcgis.com/5jNaHNYe2AnnqRnS/arcgis/rest/services/COVID19_Japan/FeatureServer/0/query?where=%E9%80%9A%E3%81%97%3E0&returnIdsOnly=false&returnCountOnly=false&&f=pgeojson&outFields=*&orderByFields=%E9%80%9A%E3%81%97

environment

• windows10
• discord.py 1.2.3
• python 3.7.3

Advance preparation

The following sites are easy to understand for creating and basics of Discord BOT using discord.py.

Create

First, create a program to download the above json file. You can easily download it using ** urllib **.

download.py

import urllib.request

def download():
    url = 'https://services6.arcgis.com/5jNaHNYe2AnnqRnS/arcgis/rest/services/COVID19_Japan/FeatureServer/0/query?where=%E9%80%9A%E3%81%97%3E0&returnIdsOnly=false&returnCountOnly=false&&f=pgeojson&outFields=*&orderByFields=%E9%80%9A%E3%81%97'
    title = 'COVID-19_data.json'
    urllib.request.urlretrieve(url, "{0}".format(title))

Next, make the BOT body.

main.py

import download
import json
from collections import defaultdict
import discord

TOKEN = 'Any token'
CHANNEK_ID = 'Any channel ID'
client = discord.Client()

#Displayed at startup
@client.event
async def on_ready():
    print('Logged in as')
    print(client.user.name)
    print(client.user.id)
    print('------')

#When you receive the message
@client.event
async def on_message(message):
    #Ignore messages from bots
    if message.author.bot:
        return
    if message.content.startswith("!count"):
        #Load json file
        download.download()
        json_open = open('COVID-19_data.json', 'r', encoding="utf-8_sig")
        json_load = json.load(json_open)
        jsn = json_load
        
        #Keep the name and number of prefectures of residence in defaultdict
        properties = defaultdict(int)
        for f in jsn['features']:
            property = f['properties']['Prefecture of residence']
            if property == 'People's Republic of China' or property == 'investigating' or property == 'unknown':
                continue
            if property not in properties:
                properties[property] = 0
            properties[property] += 1
        #It takes time to output line by line, so the output contents are saved in advance.
        say = ''
        for p in properties:
            say += p + ' ' + str(properties[p]) + '\n'
        await message.channel.send(say)

client.run(TOKEN)

The above is the BOT program that displays the number of people infected with the new coronavirus in each prefecture.

result

Data !!!!

Actually, it was output a little more, but it could not fit due to the capture size. Please note.

in conclusion

It's a rough idea, so there may be places where you can make mistakes and be smart. In that case, I would appreciate it if you could point out. The violence of the new coronavirus is still unstoppable. Please be careful.
