You see no problem with it, but it's returning that you are not printing the file output to the console. But you swear it looks right!
I had an issue where the program kept returning "You should print the contents of the file to the console" and then "Something is wrong with the code." But my code looked right.
After a reload and running the program again (the run button, not the check code button), it passed the check. Try doing those two things first.
If you are having trouble, note that you can't close the file until you've read from it! You have to store the file's contents in a variable so your program can use them.
