STEP 16: Before we update our new file in update_high_scores(), we first need to open it.

If we change open()'s second parameter to "w", we can open a file in write mode, which allows us to edit it.

If you open a file that doesn't exist in write mode, Python creates that new file for you.

• In SUBJECT, click on and drag Open in Write Mode inside update_high_scores().
• Then, change the string "my_file.txt" to the variable file_name.
