Question

List the situation(s) in which the code may result in IOError?

Answer 1

An IOError may occur when an input/output operation fails, for example:

• Opening a file that does not exist in read mode.
• Attempting to read a file without sufficient permission.
• Attempting to write to a read-only file.
• Writing when the disk is full.
• Using an invalid file path or inaccessible device.
• A hardware, network, or operating-system error during file access.

In modern Python, many such errors are represented by the more general OSError class.
