With PyGI it is possible to use Python-like constructors, or "new" functions e.g. the following are (usually) equivalent:
label = Gtk.Label()
label = Gtk.Button()
label = Gtk.Label.new()
label = Gtk.Button.new()
However, the first form is preferred: it is more Python-like. Internally, the difference is that Gtk.Label.new() translates to a call to gtk_label_new(), whereas Gtk.Label() (the preferred form) will directly construct an instance of GtkLabel at the GObject level.

expander = Gtk.Expander(label="my expander")
expander = Gtk.Expander(label="my expander")
Combining the two points above, if you wish to call a construct-like function such as gtk_button_new_with_label(), you do have the option of calling Gtk.Button.new_with_label(), however if we check the [http://developer.gnome.org/gtk3/3.2/GtkButton.html#GtkButton.properties GtkButton Construct parameters] we see one called "label" which is equivalent. Therefore gtk_button_new_with_label("foo") should be called as:
button = Gtk.Button(label="foo")
