What to Focus On
- Files store data permanently on secondary storage.
- A file is a named location used for later access.
- Python programs and data can both be stored as files.
- Text file and binary file are the two main data file types.
- Text files are human readable.
- Binary files are not human readable.
- open() creates or opens a file.
- The default mode is read mode.
- Text mode is default; binary mode needs 'b'.
Common Mistakes to Avoid
open() always opens an existing file only, so it cannot create a file.
The default mode of open() is write mode.
write() and writelines() return the same kind of result.
Memory Tips
Definition of a file
Text file versus binary file
Examples of text files
