python - Allow chained method calls in certain orders only

Question

I have a Python3 class that supports method chaining.

For example, I have methods a(), b() and c(). How can I allow c() to only be chained after a() or in another thought, how can I allow b() not to be chained next with function c()?

? a().b().c()
? b().c()
? a().c() #only allow this sequence

Is this possible?

Edit:

To define method chaining is self-explanatory in programming. It is basically calling methods in a chain.

method_a().method_b().method_c()

class Test:
   def a(self):
      ...
      return self

   def b(self):
      ...
      return self

   def c(self):
      ...
      return self
