I hope I am understanding your question...
This question is trying to determine if you know how for/in loop syntax is written.
To fill in these blanks:
groceries = ['fruit', 'tomatoes', 'paper towels', 'ketchup'] _ item _ groceries: print(item)
The first blank is "for".
The second is "in"
Basically, the code is saying "For each ordinal position in the groceries list, print that position's element/value."
And, of course, the resulting output would be:
fruit tomatoes paper towels ketchup
I hope that helps.
Stay safe and happy coding!
