If you are searching for lsp symbols you can do:
```
:Telescope lsp_dynamic_workspace_symbols
```

For this to work you need to have Neovim LSP framework to be connected to the corresponding LSP server.

In order to do that I recommend to install:
- [mason-lspconfig](https://github.com/williamboman/mason-lspconfig.nvim)

That require:
- [mason](https://github.com/williamboman/mason.nvim)
- [nvim-lspconfig](https://github.com/neovim/nvim-lspconfig)

You can then install the LSP server for Python with the Neovim command: `:MasonInstall pyright`
