We put the name of the file inside of speach marks "demo.txt" The "r" means open the file for reading only.

To read all of the file we can loop through each line like this:

We open the file "demo.txt" and append, "a", the text to the file using write:

We open the file "demo.txt" and overwrite the content "w" :
