Keras layer weights shape is different compared to other conventions

I have been looking at the layers.weights output of Keras layers. The shape of the layer weight matrix is listed as (number_of_inputfeatures, dense_layer_neurons).

The first example in docs.

However, all the theoretical courses I saw, as well as in pytorch, layers have weight matrix shape the opposite way where weight matrix shape is given by (dense_layer_neurons, input_features) or (layer_2_neurons, layer_1_neurons)

Why are these two conventions opposite to each other?

Am I missing anything? Can someone please clarify.

Thanks.
