[PYTHON] I started to work at different times, so I made a bot that tells me the time to leave

Because of the recent infectious disease, staggered commuting has started. I made a bot that tells me the time to leave when I post the time to work.

environment

python 3.6.6
Heroku

reference

For the directory structure of the SlackBot project and the cooperation with Heroku, I referred to the following site. https://qiita.com/akabei/items/ec5179794f9e4e1df203

Source code

I was able to confirm the operation of SlackBot based on the site I referred to above (I closed the fortune), so I will create a code to calculate the leaving time.

・ Calculate the leaving time using the posting time as the arrival time

from datetime import datetime, timedelta, timezone
from slackbot.bot import listen_to

@listen_to(r'^Attendance$')
def work_time(message):
    JST = timezone(timedelta(hours=+9), 'JST')

    start_now = datetime.now(JST)
    end_time = start_now + timedelta(hours=8, minutes=45)
    message.reply(end_time.strftime("%H:%M"))

Execution result ↓ ↓ キャプチャ1.PNG

If this is the case, you will have to send a message immediately after coming to work, so create a pattern that allows you to specify the time.

・ Specify the time of arrival and calculate the time of departure

import re
from datetime import datetime, timedelta, timezone

from slackbot.bot import respond_to, listen_to

@listen_to(r'^Attendance\s[0-9]+:[0-9]+$')
def work_time(message):

    JST = timezone(timedelta(hours=+9), 'JST')
    current = datetime.now(JST)

    text = message.body['text']
    result = re.match(".*\s([0-9]+):([0-9]+)", text)

    hour = result.group(1)
    minute = result.group(2)

    start_now = datetime(
        year=current.year,
        month=current.month,
        day=current.day,
        hour=int(hour),
        minute=int(minute))
    end_time = start_now + timedelta(hours=8, minutes=45)
    message.reply(end_time.strftime("%H:%M"))

Execution result ↓ ↓ キャプチャ2.PNG

No matter what time you come to work, what time is it on time? I don't have to worry

Summary

・ It was easy to deploy SlackBot and be able to interact with it (because there was an article that was summarized in an easy-to-understand manner). ・ Because many people commute to work at different times, the trains at late hours became crowded, so after all, I returned to the original time and there was no place for bots to play an active role.
