Exam 6: Files and Exceptions

A(n) _______________ file contains data that has been encoded as text, using a scheme such as ASCII.

Which step creates a connection between a file and a program?

It is possible to create a while loop that determines when the end of a file has been reached.

A(n) _______________ access file retrieves data from the beginning of the file to the end of the file.

A(n) _____ access file is also known as a direct access file.

A filename _______________ is a short sequence of characters that appear at the end of a filename preceded by a period.

What happens when a piece of data is written to a file?

When a piece of data is read from a file, it is copied from the file into the program.

What do you call the process of retrieving data from a file?

A(n) _______________ file contains data that has not been converted to text.

If a file with the specified name already exists when the file is opened, and the file is opened in 'w' mode, then an alert will appear on the screen.

The term _______________ file is used to describe a file from which the program gets data.

In Python, there is nothing that can be done if the program tries to access a file to read that does not exist.

Assume that the customer file references a file object, and the file was opened using the 'w' mode specifier. How would you write the string 'Mary Smith' to the file?

Which mode specifier will erase the contents of a file if it already exists and create it if it does not exist?

Which of these is associated with a specific file and provides a way for the program to work with that file?

What type of file access jumps directly to any piece of data in a file without reading the data that came before it?

Python allows the programmer to work with text and number files.

When a program needs to save data for later use, it writes the data in a(n) _______________.
