# turn the simplex type into symbol type

I have a list of elements of type simplex. I need them as symbols. I wrote the following:

```
import sympy as sym
S = SimplicialComplex([[0,1], [1,2], [0,2]])
Chain = S._n_cells_sorted(1)
print(type(Chain[0]))
Chain2 = []
for i in Chain:
Chain2.append(str(i))
print(Chain2[0], type(Chain2[0]))
Chain3 = [sym.symbols(v) for v in Chain2]
print(Chain3[0],type(Chain3[0]))
```

The program prints:

```
(0, 1) <class 'sage.topology.simplicial_complex.Simplex'>
(0, 1) <class 'str'>
((0, 1)) <class 'tuple'>
```

I want to turn the type elements of the initial list `Chain`

into symbols but this program turns them into tuples.

I would appreciate any help!

According to the documentation at https://docs.sympy.org/latest/modules..., if you pass a tuple to

`sym.symbols`

, it will return a tuple. This seems more like a`sympy`

question than a Sage one.
