如何使用 Python 在 Selenium Webdriver 中高效迭代变量数？

Question

I am using selenium webdriver with Python on IE and the code mentioned below is working fine but I need to make this in a loop. Please suggest. termsName0 may be 2 ,3 4 or N numbers

Code:

Select(self.driver.find_element_by_name("termsName0")).select_by_visible_text("Blank No Text")
Select(self.driver.find_element_by_name("termsName1")).select_by_visible_text("Blank No Text")
Select(self.driver.find_element_by_name("termsName3")).select_by_visible_text("Blank No Text")

Answer 1

You can use try except contract if you do not know the "N".

from selenium.common.exceptions import ElementNotVisibleException, WebDriverException, NoSuchElementException

try:
    i = 0
    while True:
        name = "termsName" + str(i)
        Select(self.driver.find_element_by_name(name).select_by_visible_text("Blank No Text")
        i +=1
 except (ElementNotVisibleException, WebDriverException, NoSuchElementException):
        pass

Answer 2

This is one way. N specifies how many times you want to loop

N = 4

for i in range(N):
    name = "termsName" + str(i)
    Select(self.driver.find_element_by_name(name).select_by_visible_text("Blank No Text")

Basically it takes the number of the current iteration and appends that to "termsName" .

Above code is equivalent to

Select(self.driver.find_element_by_name("termsName0")).select_by_visible_text("Blank No Text")
Select(self.driver.find_element_by_name("termsName1")).select_by_visible_text("Blank No Text")
Select(self.driver.find_element_by_name("termsName2")).select_by_visible_text("Blank No Text")
Select(self.driver.find_element_by_name("termsName3")).select_by_visible_text("Blank No Text")

For iterating variable number of items you could try something like this

#To fetch all elements start with termsName 
element_list = firefox_driver.find_elements_by_id("termsName[0-9]*")

# below code will iterate over the all links
for i in range(len(element_list)):
        name = "termsName" + str(i)
        Select(self.driver.find_element_by_name(name).select_by_visible_text("Blank No Text")

Hope it helps.
