Because of a deliberate decision made to delete it. Silently.
This is documented:
When an exception has been assigned using as target, it is cleared
at the end of the except clause. This is as if
except E as N:
foo
Hello
try:
a = 1 / 0
except ZeroDivisionError as ex:
pass
ex
Traceback (most recent call last):
File "", line 1, in
ex
NameError: name 'ex' is not defined
Why variable ex doesn't exist ?
