Chapter 10: Problem 7

When writing a program that performs an operation on a file, what two fileassociated names do you have to work with in your code?

Short Answer

Expert verified

Answer: The two file-associated names are the file path and the file object. The file path specifies the location of the file in the computer's storage system and consists of the drive, directories, folder, and file name separated by path delimiters. The file object is created when a file is opened using the built-in `open()` function in python, allowing you to read, write, or modify the file, and it must be closed after the operation is completed.

Step by step solution

1. File Path

The first file-associated name you need to work with in your code is the file path. The file path specifies the location of the file in your computer's storage system. It includes the drive, directories, folder, and file name separated by path delimiters. In python, you can use the built-in `os.path` library to create cross-platform file paths.

2. File Object

The second file-associated name is the file object. A file object is created when you open a file using the built-in `open()` function in python. This file object is your main point of interaction with the file, allowing you to read, write, or modify the file. It's essential to close the file object when you're done working with it, either by calling the `close()` method or using the `with` statement. Using a `with` statement, you can ensure that the file automatically closes after executing the indented code block. Now you know the two file-associated names you have to work with in your code when performing operations on a file: file path and file object.
