When Python+selenium implements webUI automation, when an exception is caused by the page loading speed, it can be solved by waiting; there are three commonly used waiting methods: 1. Forced waiting 2. Explicit waiting 3. Implicit waiting
#Force wait
module: time
Statement block: sleep(*)
Note: Forced to wait * seconds, no matter whether the page is loaded within * seconds, proceed to the next step
Features: Too mechanical affects efficiency
#implicit wait
Module: webdriver
Statement block: driver.implicitly_wait(*)
Note: * is the maximum waiting time. If the page is loaded within the specified time, the next step will be executed, otherwise it will wait until * seconds.
Features: When waiting for the page to load, all resources including js are loaded, and it acts on the entire driver cycle
# explicit wait
模块：selenium.webdriver.support.wait.WebDriverWait
Statement block: WebDriverWait(driver, total duration, interval duration, ignore exception (optional)).until()
