Error Handling

Before deploying the TSP application, it’s imperative to ensure thorough error resolution to achieve a stable and reliable release. Debugging emerges as a pivotal aspect in this context.

try-except-finally

In Python, errors are commonly referred to as exceptions. To take care of error handling, we can use the try-except block. The try statement allows us to test a block of code for errors. The except statement allows us to handle the error.

For example, if we’re trying to open a file that doesn’t exist, we can use a try statement to test for the error and an except statement to handle it. In this code block, we put the code that might raise an exception inside the try block. If an exception is raised, Python will jump to the except block. With except IOError, we specify that this block will catch exceptions of the IOError type. The IOError exception is raised when there are problems related to input/output operations, like when a file can’t be opened.
