In some languages, one may declare a dictionary's key and its value like so:

```
foo = "bar"

my_dict = { foo }
>> { "foo" : "bar" }
```

In Python, one must instead write:

```
foo = "bar"

my_dict = {
    "foo": foo
}
>> { "foo" : "bar" }
```

I humbly suggest this change as a QoL improvement for those who work with dictionaries all day.

Your proposal is not possible in Python. The object does not know under which variable names it is accessible. The closest you can get is this:

>>> dict(
...     foo="bar"
... )
{'foo': 'bar'}
