Automatic purchase bot in Python

I am Japanese and basically write articles in Japanese, but this time I decided to write in English.

This is a page that summarizes what has been done until the completion of the automatic purchase bot.
I would like to upload other articles in English as well. It takes time.
Basically, you can see it by looking at the link.
If you have any questions, please leave a comment.

A series of flows

手順1

Environment

Python環境構築-VScode-win10

手順2

Scraping with Selenium

PythonとSeleniumでスクレイピング

手順3

Easy to create while looking at the internet

手順4

Improvement of problems

Shown below

Problems found when creating

問題1

Time calculation (to perform login processing n minutes before)

Python 時間演算で詰まったこと

問題2

Element not found (resulting in a time issue)

自動購入の際の問題

問題3

Time difference in PC (detects time difference from Internet time signal)

PC内時間のズレを検出する。

問題4

Judge and correct the deviation with the if statement

Python if文

Simple operation explanation

1. Enter the URL of the ticket you want to get
2. Enter the start time
3. Detects and corrects discrepancies between PC and Internet time signals
4. Log in to the site 2 minutes ago
5. Purchase at the set start time

Roughly like this

Code

I will publish a part of the completed code for the time being.

I want to post what I made, and not everyone can do it with this code.

I hope it will serve as a reference only.

Most of them can be copied, but the code will change depending on whether it is Amazon, Rakuten, or the site for automatic purchase.

This time I used it to buy a ticket for a Japanese underground idol.

I was also able to take the reference number 1

Some things that change depending on the site, such as clicking a button or entering characters, are broken.
(Because it will change depending on the site even if it is posted)

The specific part to change is the contents of def ().

Please refer to it for other articles such as basic operation.

If you want to make it, please do your best.

I was able to make it properly even with inexperienced self-study

while True:
  schedule.run_pending()
  time.sleep(0.1)

finally

I made it while checking various things.

Even a beginner in programming could make it. It depends on your efforts.

As a result, my knowledge of Python was also good.

This completes the creation of the automatic purchase bot.

I may write articles that are still relevant, but lol

After all, the speed of purchase depends on the internet connection.
If you want to get a good number with a ticket etc., use a faster line.

Notice: Android app

I thought about purchasing tickets etc. with the Android application.
