If you did the Study Drills from the last exercise you should have seen all sorts of commands (methods/functions) you can give to files. Here’s the list of commands I want you to remember:
close – Closes the file. Like
File->Save.. in your editor.
read – Reads the contents of the file. You can assign the result to a variable.
readline – Reads just one line of a text file.
truncate – Empties the file. Watch out if you care about the file.
write('stuff') – Writes “stuff” to the file.
For now, these are the important commands you need to know. Some of them take parameters, but we do not really care about that. You only need to remember that
write takes a parameter of a string you want to write to ...
