When programming in Python, exceptions are used to manage errors or exceptional situations that may arise during program execution. To handle exceptions, we make use of the try-except block. The try-except block enables us to write code that could potentially trigger an exception and specify how we want to deal with that particular exception if it occurs.
The structure of the try-except block is as follows:
Inside the try block, we place the code that we suspect could lead to an exception being raised. If an exception does occur within the try block, the program flow immediately jumps to the corresponding except block. The except block specifies the type of exception it can handle. If the exception raised matches the specified type, the code inside the except block is executed. If the exception type does not match, the except block is skipped. The exception is passed up to the next try-except block or the outer level.
