[New-bugs-announce] [issue39909] Assignment expression in assert causes SyntaxError

[Михаил Кыштымов]

New submission from Михаил Кыштымов <mister.rend at gmail.com>:

Assignment expression in assert causes SyntaxError

Minimal case:
```
assert var := None
```

Error:
```
  File "<input>", line 1
    assert var := None
               ^
SyntaxError: invalid syntax
```

Workaround:
```
assert (var := None)
```

My use case:
```
my_dict = dict()
assert value := my_dict.get('key')
```
