qdot
qdot will help you quickly dive into data. Either you have a value, or you have a None.
This is what you want when you are looking for something convenient like in JavaScript, yet at the same time allow for more Pythonic code.
Case 0: Hello Dot
from qdot import Dot
d = {"a": 1, "long name": 2}
d = Dot(d)
assert d.a == 1
assert d.a.a.a == None
assert d["long name"] == 2Case 1: Quick default / ternary
from qdot import Dot
result = Dot(None) or Dot(10)
assert result == 10 # comparison operators have been implemented: no surprises
# and
result = Dot({}).a.a.a.a
result = result if result else 15
assert result == 15Case 2: Getting data from an API
from qdot import dot
@dot
def get_from_api(arg):
return {"a": arg}
assert get_from_api(1).a.a.a == NoneSetting values
Is not allowed directly
but, it works by having an "original_object".
You only have to do 1 comparison in total:
from qdot import dot
@dot
def get_data_from_api():
return {"a": {"b": {"c": 1}}}
data = get_data_from_api()
interesting = data.a.b.original_object
if interesting:
interesting["d"] = 2
interesting
{'c': 1, 'd': 2}
data
Dot({'a': {'b': {'c': 1, 'd': 2}}})JSON Serialization
d = Dot(1)
json.dumps(d.original_object)
json.dumps(Dot(1), default=lambda d: d.original_object)Bonus: Getting data from a function which might throw
This is probably frowned upon? Caught exceptions will return Dot(None).
from qdot import trydot
@trydot(TypeError)
def return_impossible():
return {} + []
assert return_impossible() == None
