这里通过使用随机数随机决定滚动距离。

from time import sleep
    
    from selenium import webdriver
    from selenium.webdriver import ChromeOptions
    import random
    
    
    def scroll(_browser):
        temp_height = 0
        scroll_height = 100
        while True:
            scroll_height += 1000*random.random()
            # _browser.execute_script('window.scrollTo(0, document.body.scrollHeight)')
            _browser.execute_script('window.scrollTo(0, '+str(scroll_height)+')')
            check_height = _browser.execute_script(
                "return document.documentElement.scrollTop || window.pageYOffset || document.body.scrollTop;")
            # 如果两者相等说明到底了
            if check_height == temp_height:
                break
            temp_height = check_height
            print(check_height)
            sleep(2)
    
    
    if __name__ == '__main__':
        option = ChromeOptions()
        option.add_experimental_option('excludeSwitches', ['enable-automation'])
        browser = webdriver.Chrome(executable_path='chromedriver.exe', options=option)
        try:
            # 对指定的url发起请求
            browser.get('https://www.runoob.com/python/python-strings.html')
            sleep(1)
            scroll(browser)
            # 执行js，让滚轮向下滚动
    
        except Exception as e:
            print(e)
        finally:
            browser.quit()
