org-babel call other python block automatically

Question

I have two python blocks. If I execute blockA, then execute blockB, it works fine. How can I only execute blockB without manually executing blockA? I am thinking add a :var from blockA` but it does not work:

#+name blockA
#+begin_src python :session :results output
def funcA():
    print("funcA")
    return
#+end_src

#+RESULTS:

#+name blockB
#+begin_src python :session :results output :var x=blockA
def funcB():
    funcA()
    print("funcB")
    return

funcB()
#+end_src

Answer 1

You are missing colons after the #+name. This works fine:

#+name: blockA
#+begin_src python :session :results output
def funcA():
    print("funcA")
    return
#+end_src

#+name: blockB
#+begin_src python :session :results output :var x=blockA
def funcB():
    funcA()
    print("funcB")
    return

funcB()
#+end_src

#+RESULTS: blockB
: funcA
: funcB
