Setting a default for nosuchelementexception for multiple variables in python

Question

So I am scrapping multiple rows of a table and many of them are either available or not for different pages. What I want to do is to detect which field is not available and supply it on a variable and set a default variable i.e., None to it. For eg,

try:
        field1 = driver.find_element(By.XPATH, value="somexpath")
        field2 = driver.find_element(By.XPATH, value="somexpath")
        field3 = driver.find_element(By.XPATH, value="somexpath")
        field4 = driver.find_element(By.XPATH, value="somexpath")
        field5 = driver.find_element(By.XPATH, value="somexpath")

        dict_ = {"field1":field1, "field2": field2.....}

except NoSuchElementException:
       # some code to detect which element not found and supply a default value None to it
       defaultVaule = None

Please help.

Answer 1

You can inject if else None statement as follows:

field1 = driver.find_element(By.XPATH, value="somexpath")
field1=field1.text if field1 else None

Answer 2

You may want to reverse the order - initialize using default values and populate if retrieval succeeds element-wise.

dict_ = {"field1":None, "field2": None.....}

try:
        dict_["field1"] = driver.find_element(By.XPATH, value="somexpath")
try:
        dict_["field2"] = driver.find_element(By.XPATH, value="somexpath")
