How to pass gobject.Gtype arguments to a Gtk.ListStore in a function

Question

I would like to pass to a function a list of types and data to register a Gtk.ListStore object. It works with a single type, passed directly as an argument, but as soon as there are several types it is necessary to use a container (list?). And in this case, I do not know how to rebase these types (str, int, etc.) into gobject.Gtype. If anyone has a solution that would be great. Sample code below.

thank you in advance.

# Fonctions
def initListStore(lesTypes, laListe):
  leStore = Gtk.ListStore(gobject.Gtype(lesTypes))
  for item in laListe:
    leStore.append(item)
  return leStore

# Appli
liste = [('Albert','Einstein'),('Salvador','Dali'),('Alexandre','Dumas')]
lesTypes = 'str str'
lsAuteurs = initListStore(lesTypes,liste)
for row in lsAuteurs:
  print (row[:])

Here is one possible solution:

from gi.repository import Gtk
def initListStore(lesTypes, laListe):
    leStore = Gtk.ListStore()
    leStore.set_column_types(lesTypes)
    for item in laListe:
      leStore.append(item)
    return leStore

# Appli
liste = [('Albert','Einstein'),('Salvador','Dali'),('Alexandre','Dumas')]
lesTypes = (str, str)
lsAuteurs = initListStore(lesTypes,liste)
for row in lsAuteurs:
    print (row[:])
