Python except Exception as e

We can define an exception as an event, which, when raised, can alter the flow of the program. Exceptions are mainly the outcome of any given program being logically correct while still giving an error on the execution of the code. In most cases, however, this error cannot alter the execution of the program. It rather alters or changes the default flow and functioning of the program.

We can handle Python exceptions by using the try...except block.

This tutorial demonstrates the difference between the except statement and the except Exception as e statement in Python.

In Python, both these statements are utilized to implement exception handling. However, these two statements do have a significant difference between them, not just the syntax.

The simple except statement is utilized in general cases, and it excepts all the exceptions. In contrast, the except Exception as e statement is a statement that defines an argument to the except statement.

e in the latter statement is utilized to create an instance of the given Exception in the code and makes all of the attributes of the given Exception object accessible to the user.

While the except Exception as e statement is much more in-depth, it does not deliver on catching exceptions like BaseException or some of the system-exiting exceptions like KeyboardInterrupt, SystemExit, and also GeneratorExit. However, a simple except statement can fulfill this task and catches all these exceptions.

The syntax for the simple except statement is:

try:
    # write code that may throw exception
except:
    # the code for handling the exception

While the syntax for the except Exception as e statement is:

try:
    # write code that may throw exception
except Exception as e:
    # the code for handling the exception
