That depends on the kind and state of layers You want to count:
# All layers (as listed in TOC, included: "non-drawable" and invalid layers)
layers = QgsProject.instance().layerTreeRoot().findLayers()
# list-items: "QgsLayerTreeLayer"
# All valid layers (included: "non-drawable"-layers):
layers = QgsProject.instance().mapLayers()
# list-items: layer-id
# Only visible, valid and "drawable" layers:
layers = iface.mapCanvas().layers()
# list-items: layer
for layer in layers:
print(layer)
print(len(layers))
