1. Install PyCharm. There are many online tutorials.
2. Install the Selenium library.
Selenium supports many browsers, and I chose Firefox.
Since I am in a Python3 environment and have PIP installed with it, selenium is installed directly using PIP
Installation method:
— Open CMD;
— Enter Python36/Scripts (find the directory below);
— Enter the command PIP install selenium;
— Press Enter to wait for automatic installation;
— If the last line of code says “Successfully install Selenium -xx”, the installation is successful.
3. The FireBug plug-in
FireBug is a firefox plugin that allows you to quickly locate code elements. Selenium focuses on locating elements, and only after locating elements in place can you proceed to the next step.
Installation method:
Open the Firefox browser and click the button in the upper right corner
— Click add-ons
— Click Expand
– search firebug
Click Install and restart the browser
— The test installation is successful. Press F12 to display the following screen, indicating that Firebug has been successfully installed
Install the GeckoDriver (in Windows).
The file is linked below.
Usage:
1, download complete decompression;
2. Place geckodriver in the path of the browser executable
3. Add to environment variables
5. Set the pycharm
Start by creating a project
Open PyCharm -> Open File -> Click Setting -> click the Settings button on the far right
Click Add in Virtualenv Environment and System Interpreter and select the python runtime folder given in this article. Location is an empty working folder.
Open PyCharm -> Open File -> Click Setting
Set Project Interpreter to the file given in this article, or to your own python runtime
6. Create a Python file
Enter the following program:
# -*- coding: utf-8 -*-
from selenium import webdriver
driver = webdriver.Firefox()

The result is as follows:
Successfully set up the environment.

def buy(buytime):
while True:

# Compare the time and click settle when the time is up
if now > buytime:
try:
Click the settlement button
if driver.find_element_by_id(“J_Go”):
driver.find_element_by_id(“J_Go”).click()
Driver.find_element_by_link_text (‘ Submit order ‘).click()
except:
Time. Sleep (0.1)
print(now)
