Question About Section 2.1.1 - Getting Started

Towards the end of Section 2.1.1, the following statement is written when using torch.tensor() to create a new tensor from Python lists.

Here, we construct a matrix with a list of lists, where the outermost list corresponds to axis 0, and the inner list to axis 1.

Even though I understand what an axis is, I do not get how the definition applies to the tensor created by using the Python lists. How does the outermost list (which was [4, 3, 2, 1]) correspond to axis 0? Thank you so much!
