*python eoferror when reading a line*
in python, an eoferror (end of file error) occurs when a program tries to read beyond the end of a file or input stream. this error is commonly encountered when using functions like `input()` or `readline()` to read input from the user or a file.
when a program reaches the end of a file or input stream and tries to read more data, an eoferror is raised to indicate that there is no more data to be read.
*example:*
let's create a simple python program that reads lines from a file until it reaches the end of the file and triggers an eoferror:
in this example, we are trying to read lines from a file named `sample.txt` using a `while` loop and the `readline()` method. when the program reaches the end of the file, the `readline()` method will return an empty string, indicating that there are no more lines to read. the `if not line:` condition checks for this empty string and breaks out of the loop.
if the program tries to read beyond the end of the file, an eoferror will be raised. the `except eoferror:` block catches this error and prints a message indicating that the end of the file has been reached.
*note:* it's important to handle eoferrors properly in your code to prevent crashes and make your program more robust when dealing with input streams and files.
