Function first_name and last_name coursera

I am stuck with my code on my assestment. I have passed with sufficient score but I dont like to leave any question on fail- for my own learning. I manaed to get all statements, apart from the last one, where if first and last name are black, the output should be empty. But I am still getting Name - this word shoul dnot be there at all.

Thanks a lot!

   # code goes here
 if len(first_name)==0:
   string="Name: "+last_name
   
 elif len(last_name)==0:
   string="Name: "+first_name

 elif len(last_name)==0 and len(first_name)==0:
   string=""    

 else:
   string="Name: "+last_name+", "+first_name

 return string 

print(format_name("Ernest", "Hemingway"))
# Should return the string "Name: Hemingway, Ernest"

print(format_name("", "Madonna"))
# Should return the string "Name: Madonna"

print(format_name("Voltaire", ""))
# Should return the string "Name: Voltaire"

print(format_name("", ""))
# Should return an empty string

Name: Hemingway, Ernest
Name: Madonna
Name: Voltaire
Name:

The if-elif-else statement exits on the first met condition. Therefore you should wisely define the order of conditions

What's going wrong

It is impossible for you to reach the condition where len(last_name)==0 and len(first_name)==0:.

This is because either your first conditional: if len(first_name)==0: or your second conditional: elif len(last_name)==0: will always be true before reaching that.

An easy fix

The easy solution here is to move that more complex condition as the first one in your if,elif,else chain.
