def add_greetings(names):

 for name in names:

   count = 0
   print("Hello, " + name)
   count += 1

print(add_greetings(["Owen", "Max", "Sophie"])

Output: Hello Owen
Hello Max
Hello Sophie
None
What’s Wrong with my code, Why none occurs despite of count definition?

A function that completes its execution without output e.g. no return will always return None. Why might this be printed?

I found this error. Despite adding the return statement “return names” code is appearing with a different Output: Hello Owen,
Owen

What did you want to print? Does your code reflect that? It won’t be printing an output unless you asked for one.

The output must be printed like this: Hello Owen
Hello Max
Hello Sophie
Within a List

What seciton of your code is responsible for printing each of these lines? Is it the same part, or more than one?
