Answer:
A top-level domain or the TLD is the domain at the highest level in the hierarchy of the DNS. And that means in the Internet DNS. Also, the top-level domain is installed in the namespace toot zone. And the top-level domain is the .com, in general, to be named as the best one. The next two are the .net and .org. But since it is required to optimize the website for the mobile devices, we should select here .com.

A formula in Excel will ALWAYS start with = then the function name like
=SUM(A1:A5)
Answer:
def validateCreditCard(x):
if type(x)==str and len(x) == 8:
print("Valid credit card number")
else:
print("Invalid credit card number")
validateCreditCard("43589795")
Explanation:
Run the code on your text editor(vs code, sublime, pycharm ) you will get your desired response. If your input is not of type string and not up to 8 digit you will get the response "invalid credit card number" but if it is of type string and up to 8 digit you will get "Valid credit card number".
But remember python works with indentation so when you are transferring this code to your text editor it will run properly well.
I defined the code using the conventional pattern "def"
After defining the function you create a brackets (x) to accommodate your argument x and end it with a semi colon.
Then i use "if" statement to make sure only string argument and 8 digit value will be accepted to print a "valid credit card". if your argument does not pass the if statement condition it will print out the else statement condition which is "Invalid credit card number"
Finally, you have to call your function and test various values.
