The tutorial likely predates if/else expression syntax introduced in
2.5, which would be spelled as:

button = gtk.Button("True" if fill else "False")

BTW adding "==True" to a boolean value is redundant and can even break
for logically true values that don't compare equal to True (such as the
number 10 or the string "foo").
