We can count the number of columns in a table in Selenium. The headers of a table are represented by <th> tag in html and always in the first row of the table. The rows are identified with <tr> tag in html. The total count of the number of column headers is mostly equal to the total number of columns. A <th> tag’s parent is always a <tr> tag.
The logic is to get all the headers. We shall use the locator xpath and then use find_elements_by_xpath method. The list of headers will be returned. Next we need to compute the size of the list with the help of len method.
The html code snippet of a table column count is as described below −
Code Implementation for getting total column count.
from selenium import webdriver #browser exposes an executable file #Through Selenium test we will invoke the executable file which will then #invoke actual browser driver = webdriver.Chrome(executable_path="C:\\chromedriver.exe") # to maximize the browser window driver.maximize_window() #get method to launch the URL driver.get("https://www.tutorialspoint.com/plsql/plsql_basic_syntax.htm") #to refresh the browser driver.refresh() # identifying the header from row1 having <th> tag cols = driver.find_elements_by_xpath("//table/tbody/tr/th") # len method is used to get the size of that list print(len(cols)) #to close the browser driver.close()
