--description--

The range() function returns an immutable sequence of numbers. As you can see, the data type of rods['A'] is range, but you want it to be a list.

Pass your range() call to the list() function to do that.

--hints--

You should pass your range() call to the list() function.

({ test: () => assert(runPython(`
  rods['A'] == list(range(3, 0, -1))
  `))
})
