You should understand that an object may have different names:

```
sage: p = 3
sage: q = p
sage: id(p)
529391024
sage: id(q)
529391024
```

Here, `p`

is the name of the same object than `q`

(i mean, they both are the name of the same location in memory). Hence, your question is not well defined, since Sage (or Python) will not be able to make a difference between `p`

and `q`

. If you need such a feature, there may a better way to write your progam.

That said, you can try to look for your variable in the `globals()`

dictionary:

```
sage: def my_name(p):
....: for name, value in globals().items():
....: if id(value) == id(p):
....: return name
sage: my_name(p)
'p'
sage: my_name(q)
'p'
```

That said, this is quite a dirty method, and you should consider avoiding it.
