Any help will be highly appreciated!

while True:
    links = [link.get_attribute('href') for link in driver.find_elements_by_xpath("//a[(contains(@title,'公司债券')and not(contains(@title,'短期'))]")]
    for link in links:
               driver.get(link)
               #dosth

Answer 1

There is an extra bracket in you xpath, use

links = [link.get_attribute('href') for link in driver.find_elements_by_xpath("//a[contains(@title,'公司债券')and not(contains(@title,'短期'))]")] 

instead You can use chrome developer tools first to validate your xpaths PS: I changed the xpath here a bit to be able to find some elements in my page

Answer 2

There should be space before and . Also there is extra leading bracket in your XPath. Try:

"//a[contains(@title,'公司债券') and not(contains(@title,'短期'))]"
