1. Basics of Files and Types of Files
- Files are used to store data permanently instead of only keeping it in memory during program execution.
- There are mainly two types of data files: text file and binary file.
- Text files contain only the ASCII equivalent of the contents and are human readable.
2. Opening and Closing Files
- open() creates a new empty file if the file does not exist.
- The default access mode for open() is read mode.
- By default, files are opened in text mode; binary mode requires b.
3. File Access Modes
- r means read only and the file object starts at the beginning of the file.
- rb means binary read only and the file object starts at the beginning of the file.
- r+ or +r means read and write and the file object starts at the beginning of the file.
