I think this works; not sure if it is better. The list() calls are not
needed if tarray and the result of funcB are already lists; the tuple
calls may not be needed either:
def funcA(tarray):
a = [2,3,4]
if len(tarray) >=3:
return tuple(a)
result = list(tarray) + list(funcB(3-len(tarray)))
return tuple(result[:3])
