This code prints two lines of text to the screen: first "Hello world!" using double quotes, then "hi" using single quotes. Both are valid string literals in Python, so the code runs without errors.

- Notice that Python allows both single and double quotes for strings; try changing the quotes around one of the words to see if the output changes.
- If you want to print both words on the same line, think about how the print function separates multiple arguments or how you could combine the strings.
