Cats and Dogs: Make two files, cats.txt and dogs.txt. Store at least three names of cats in the first file and three names of dogs in the second file. Write a program that tries to read these files and print the contents of the file to the screen. Wrap your code in a try-except block to catch the FileNotFound error, and print a friendly message if a file is missing. Move one of the files to a different location on your system, and make sure the code in the except block executes properly.

Key Concepts

File I/O

File input/output is a fundamental concept in programming that involves reading data from and writing data to files stored on disk. It allows programs to persist data across sessions and to interact with the filesystem, making it possible to create, open, read, write, and close files, among other operations.

Exception Handling

Exception handling is a mechanism for gracefully managing errors that occur during program execution. It allows a program to continue running or exit in a controlled manner when an exceptional situation, such as an unavailable file, is encountered.

Try-Except Block

A try-except block is used in programming to handle exceptions that may occur during the execution of a block of code. The try part wraps code that might raise an error, while the except block catches and processes the error, preventing the program from crashing and enabling the display of user-friendly messages.

FileNotFound Error

The FileNotFound error is a specific type of exception that is raised when an attempt to open a file fails because the file does not exist at the specified location. Handling this error allows the program to inform the user about the missing file and to take corrective actions without terminating unexpectedly.
