2020This chapter describes computer file systems, the use of paths to identify folders and files, and the “os” module in Python. We further describe opening and closing files, for both reading and writing, using Python.

We can use an editor to create text data files. We first consider, in this chapter, extracting (and inserting) data objects from (and to) data file streams.
