Error handling in programming is a crucial aspect that ensures a program can manage unexpected situations gracefully. The concept revolves around using exception handling mechanisms to deal with errors that occur during the execution of a program.

In many programming languages, this is achieved through a structure known as “try-except-finally.” The “try” block is where you write the code that you anticipate might cause an error. If an error occurs within this block, the program execution is transferred to the “except” block. This block contains code that handles the error, allowing the program to continue running or to gracefully terminate. Finally, the “finally” block is used for code that needs to run regardless of whether an error occurred or not. This is often used for cleanup operations, such as closing files or releasing resources.

By using these blocks effectively, programmers can create more robust and reliable applications that can handle unexpected issues without crashing.
