Answer:
Replace the first blank with:
message = "Hello " + name + ". Your lucky number is " + str(number)
Replace the second blank with:
return message
Explanation:
The first blank needs to be filled with a variable; we can make use of any variable name as long as it follows the variable naming convention.
Having said that, I decided to make use of variable name "message", without the quotes
The next blank is meant to return the variable on the previous line;
Since the variable that was used is message, the next blank will be "return message", without the quotes
