First thing to know is that the print() function can take mutilple paramerters :

• object - Your string or variable where you have stored some value
• seperator character - The character you want to use to seperate "objects"
• end character - Character that follows the object(s)
• output format - Where you want to Print/Write default sys.stdout
• flush option - Boolen to flush or not default False

'\n' is a special character that means new line. Thus sep= '\n' means seperate each object with a new line.
