   I also think it will be a good idea, to distinguish the icon so it is more "Python" specific!

   Sharing media and context from merged PR #26141 for verification:

   

   Terminal REPLs launched by the extension only set a title, so VS Code fell back to the default shell/profile icon. This threads an optional iconPath through the terminal creation pipeline and sets ThemeIcon('snake') for the REPL only.

   Changes

   • common/terminal/types.ts: TerminalCreationOptions gains iconPath?: TerminalOptions['iconPath'], keeping the internal type aligned with the VS Code API.
   • common/terminal/service.ts: ensureTerminal forwards iconPath on both creation paths — ensureTerminalLegacy(...) (env extension, whose options extend TerminalOptions) and terminalManager.createTerminal(...).
   • terminals/codeExecution/terminalCodeExecution.ts: new protected terminalIcon?: TerminalOptions['iconPath'], passed to terminalServiceFactory.getTerminalService(...) alongside the title.
   • terminals/codeExecution/repl.ts: sets the icon, so plain Python terminals, Django shells, native REPL tabs, and user-typed python sessions are untouched.

   // repl.ts
   this.terminalTitle = 'REPL';
   this.terminalIcon = new ThemeIcon('snake');

   Tests

   • terminalCodeExec.unit.test.ts: the title matcher now also asserts the expected icon id per suite — snake for ReplProvider, none for the Terminal and Django providers.
   • service.unit.test.ts: two tests assert iconPath reaches terminalManager.createTerminal(...) and, with useEnvExtension() stubbed on, ensureTerminalLegacy(...).

   The env-extension test stubs ensureTerminalLegacy with a plain object rather than a TypeMoq mock: dynamic mocks answer any property access, so awaiting one hangs on the phantom then.
