Question

I'm trying to retrieve data from the dynamic web table in selenium python but errors in a console as ERROR as "

TypeError: must be str, not int

FAILED (errors=1)

class DynamicWebTable1(unittest.TestCase):


@classmethod
def setUpClass(cls):
    chrome_driver_path = os.path.abspath('..')  + "\\Drivers\\chromedriver.exe"

    cls.driver=webdriver.Chrome(chrome_driver_path)

    cls.driver.implicitly_wait(30)
    cls.driver.maximize_window()
    # navigate to the application home page
    cls.driver.get("http://qavalidation.com/demo/")

def test_get_table_data(self):
    time.sleep(10)
    columns = len(self.driver.find_elements_by_xpath(".//*[@id='table01']/tbody/tr[1]/td"))
    rows = len(self.driver.find_elements_by_xpath(".//*[@id='table01']/tbody/tr"))
    print("rows - ",rows)   # rows -  3
    print("columns - ",columns) #columns -  4

    for row in range(rows):
        for col in range(columns):
            values = self.driver.find_element_by_xpath(".//*[@id='table01']/tbody/tr["+row+"]/td["+col+"]").text
            print(" Dynamic web table index {row} ,{col} value is {values} ".format(row, col, values))

Answer 1

This error message...

TypeError: must be str, not int

...implies that while at the mentioned line your program expects a String type of argument where as an Interger type of argumnent was passed to it.

To retrieve the data from the dynamic web table you need to change the line of code as follows :

for row in range(rows):
    for col in range(columns):
        values = self.driver.find_element_by_xpath('.//*[@id="table01"]/tbody/tr["'+row+'"]/td["'+col+'"]').text

Answer 2

You can't add string and integer :

>>> "1"+2
Traceback (most recent call last):
  File "<input>", line 1, in <module>
    "1"+2
TypeError: must be str, not int

You have to convert int to str :

>>> "1"+str(2)
'12'

Answer 3

It is expecting string value but you are passing int value. It happens when we concatenate string to integer. Please change the following line in your code.

values = self.driver.find_element_by_xpath(".//*[@id='table01']/tbody/tr["+row+"]/td["+col+"]").text

to

values = self.driver.find_element_by_xpath(".//*[@id='table01']/tbody/tr["+str(row)+"]/td["+str(col)+"]").text

It may resolve your issue.
