Basic usage of Python automation

One, initialize the browser driver

Import module file

from selenium import webdriver

Initialize the browser as chrome browser

browser = webdriver.Chrome()

Initialize the browser as firefox browser

browser = webdriver.Firefox()

Initialize the browser as an interfaceless chrome browser

option = webdriver.ChromeOptions()
option.add_argument("headless")
driver = webdriver.Chrome(chrome_options=option)

Second, set the browser size

#设置浏览器大小为全屏
maximize_window()：
#设置浏览器分辨率为：500×500
set_window_size(500,500)：

from selenium import webdriver
import time  

browser = webdriver.Chrome()
#设置浏览器大小：全屏
browser.maximize_window()   
browser.get('https://www.baidu.com')  
time.sleep(2)

 # 分辨率 1280*800  
browser.set_window_size(500,500) 
time.sleep(2)

# 分辨率 1024*768 
browser.set_window_size(1024,768)   
time.sleep(2)

Three, refresh the browser page

#方法：刷新浏览器页面
refresh()
from selenium import webdriver
import time  

browser = webdriver.Chrome()
 #设置浏览器大小：全屏
browser.maximize_window()  
browser.get('https://www.baidu.com')  
time.sleep(1)

try:
    browser.refresh()  #刷新页面
    print('刷新页面')
except Exception as e:
    print('test fail')

#输出内容：刷新页面

Fourth, the browser back and forward

#后退
back()
#前进
forward()
from selenium import webdriver
import time  

browser = webdriver.Chrome()
 #设置浏览器大小：全屏
browser.maximize_window()  
browser.get('https://www.baidu.com')  

#点击打开百度新闻页面
browser.find_element_by_link_text('新闻').click()
time.sleep(2)

#后退：回到百度首页
browser.back()  
time.sleep(2)

 #前进：前进到百度新闻页面
browser.forward() 
time.sleep(2)
