Selenium-如何使用python在xpath中添加整数变量

Question

Im new with selenium/python and that my problem: I have a simple site with a couple of news. I try to write script that iterates over all news, open each one, do something and goes back to all other news All news have same xpath, difference only with last symbol - i try to put this symbol as variable and loop over all news, with increment my variable after every visited news:

     x = len(driver.find_elements_by_class_name('cards-news-event'))
            print (x)
            for i in range(x):
     driver.find_element_by_xpath('/html/body/div[1]/div[1]/div/div/div/div[2]/div/div[3]/div/div[1]/div/**a["'+i+'"]**').click()
     do something                
      i = i+1

Python return error: "Except type "str", got "int" instead. Google it couple of hours but really can't deal with it Very appreciate for any help

Answer 1

You are trying to add a string and a int which is is why the exception. Use str(i) instead of i

xpath_string = '/html/body/div[1]/div[1]/div/div/div/div[2]/div/div[3]/div/div[1]/div/**a[{0}]**'.format(str(i))    
driver.find_element_by_xpath(xpath_string).click()

In the above the {0} is replaced with str(i). You can use .format to substitute multiple variables in a string by providing them as positional values, it is more elegant and easy to use that using + to concatenate strings.
