Hey Daniel Liew Yew Onn, good question. An
except statement handles specific errors that might arise during execution of the code following the
try. The raised exception is an instance that has attributes.
According to the docs:
The except clause may specify a variable after the exception name. The variable is bound to an exception instance with the arguments stored in instance.args.
as err says "allow me to refer to the raised exception by the variable name
err". Using the
err reference, the exception attributes may be accessed. If the
err instance has a
__str__ method defined, then a
print(err) will call that method and a string will be output.
Post back if you need more help. Good Luck!!

Where is the err variable defined? If there are 2 types of errors in the code, how will it know which one the err is referring to?
