May be just creator_account=self.creator_account, created_time=self.now()? Lines 228-231 could be removed after that.

Unfortunately, that won't work, since self is not defined at the moment of evaluation.

>>> class A(object):
...     def __init__(self):
...             self.a = 'abc'
...     def x(self, param=self.a):
...             print(param)
...
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 4, in A
NameError: name 'self' is not defined

Since those files (tx-example.py and blocks-query.py) are not tested in CI, the branch will be merged without waiting for CI.
