[Python-Dev] Why does "except Ex as x" not restore the previous value of x?

17 Nov 2020

      Hi,

I'm wondering why
```
x = "value"
try:
     1/0
except Exception as x:
     pass
```

does not restore "value" to x after
the `except` block.

There doesn't seem to be an explanation for this behavior in the docs or 
PEPs, that I can find.
Nor does there seem to be any good technical reason for doing it this way.

Anyone know why, or is just one of those unintended consequences like 
`True == 1`?

Here's an example of restoring the value of the variable after the 
`except` block:
...
...
...
def f(x):
...     try:
...         1/0
...     except Exception as x:
...         pass
...     return x
...
f("hi")
'hi'
Cheers,
Mark.
