Explanation
Python categorize files broadly into two types: binary files and text files.
- Binary files — These files store the information in the form of a stream of bytes.
- Text files — These files store the information in the form of a stream of ASCII or Unicode characters.
Text files include CSV (Comma-Separated Values) and TSV (Tab-Separated Values) files because they contain human-readable text data and are specific types of delimited text files. In CSV files, fields are separated by commas, while in TSV files, fields are separated by tabs.
