Question

driver.get('https://github.com/avassalotti')
contributions = driver.find_elements_by_xpath(".//ul[@class='filter-list small']//li") 
print(contributions)
for item in contributions:
    print (item)
    print(item.text)
    item.click()
    time.sleep(3)
    contribution = driver.find_element_by_xpath(".//*[@class='f4 text-normal mb-2']").text
    print(contribution)

程序适用于此链接（https://github.com/alex）而不适用于（https://github.com/agronholm,https://github.com/avassalotti）。

任何解决问题的建议。

代码块：

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

years = []
options = webdriver.ChromeOptions() 
options.add_argument("start-maximized")
options.add_argument('disable-infobars')
driver=webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
driver.get("https://github.com/agronholm")
contributions = WebDriverWait(driver, 5).until(EC.visibility_of_all_elements_located((By.XPATH, "//div[@class='profile-timeline-year-list js-profile-timeline-year-list bg-white js-sticky float-right col-2 pl-5']/ul[@class='filter-list small']//li/a")))
for item in contributions:
    print(item.get_attribute("innerHTML"))
    years.append(item.get_attribute("href"))
for year in years:
    driver.get(year)
    print(WebDriverWait(driver, 5).until(EC.visibility_of_element_located((By.XPATH, "//div[@class='js-yearly-contributions']//h2[@class='f4 text-normal mb-2']"))).get_attribute("innerHTML"))
