1. Rows in a CSV file represent individual data records, with each row containing values for the different columns or fields.
2. When working with files in different locations, the file path is used to specify the exact location of the file on the computer or network.
3. Rows in a CSV file can be accessed and manipulated using Python's built-in CSV module, which provides functions for reading, writing, and processing the data.
4. The number of rows in a CSV file corresponds to the number of data records or observations stored in the file.
5. Rows in a CSV file can be filtered, sorted, or transformed using Python's data manipulation and analysis tools, such as Pandas.
