The code prints the text "Hello world!" and then the rest of the lines are plain text, not Python code. Python will try to read those lines as code, which will cause a syntax error. - The lines after the print statement are not valid Python; if you want them as text, they need to be inside a string or a comment. - Decide whether your task is only to print "Hello world!" or to output the historical text as well, and make sure every line is either valid Python or marked as a comment.
