Try Except Block

The try-except block in Python is a fundamental construct used for handling exceptions that may occur during the execution of a program. It allows developers to write code that can gracefully handle errors without crashing the program. The basic syntax involves placing the code that might raise an exception inside the try block, followed by one or more except blocks that define how to handle specific exceptions.

However, it’s important to use try-except judiciously. Overusing it can lead to obscured errors, making debugging more difficult. For instance, some developers, especially beginners, tend to wrap large sections of code in try-except blocks, which can hide underlying issues rather than reveal them. Instead, it’s often better to let exceptions propagate naturally, as this can provide clearer insights into what went wrong 12.

Additionally, there are alternative methods for handling exceptions, such as using the contextlib’s suppress function, which can be more elegant for known exceptions that you wish to ignore 3.
