either in a list, or set, or presumably any
iterable collection, in addition to taking an
actual dictionary.
That function can be simplified:
def any_as_dict(*args, **kwargs):
return dict(args[0]) if args else kwargs
any_as_dict(a=1,b=2)
{'a': 1, 'b': 2}
any_as_dict({'a':1, 'b':2})
{'a': 1, 'b': 2}
any_as_dict([('a',1), ('b',2)])
{'a': 1, 'b': 2}
any_as_dict({('a',1), ('b',2)})
{'b': 2, 'a': 1}

Emending my own note from moments ago:

if len(args) == 0:
my_dict = kwargs
elif type(args[0]) == type(dict()):
my_dict = args[0]
else:
my_dict = dict(args[0])
print(type(my_dict),my_dict)
>>> any_as_dict(a=1,b=2)
{'a': 1, 'b': 2}

Re: Help building python application from source
Thanks for the comments. > (To make OP's requirements plainly visible, note that this appears to > be a cryptocurrency application.) Correct. It is a software that does not store private keys but acts as a server to serve lightweight wallets that would connect to it remotely. Electrumx does not store or generate private keys but my concern is running binary blobs that someone else created. The advantages of open source software only apply if you can confirm it was created from the source code. This is why I compile everything I can or use binaries based on reproducible build process. I am also wanting to run electrumx in a virtual environment under a dedicated user account on the linux box with lowest privileges. And the reason I want to be able to build from a local directory so that I can be self sufficient and be able to archive the software source code and all needed dependencies to spin up other servers or replace the server in a post disaster situation where internet or python pip package servers might be down. My bitcoin server also has very strict firewall rules that would inhibit the ability to connect to python servers. This is why I want to download the all the source code on my laptop then transfer to the server. But there are SO MANY dependencies. Electrumx has a few dependencies then each of those dependencies have more dependencies and on and on. I guess it might be possible to do what I want by manually downloading the source code of the close to 20 dependencies, manually verify the git tags and signatures. Then "python setup.py install" each one individually in the right order. This might work? I didn't know if there was an easier way. I did find out I could "pip download -r requirements.txt" but this downloads binaries specific for x86. My cpu architecture is aarch64. Is there a way to pip download -r requirements.txt source only or specify aarch64?

(To make OP's requirements plainly visible, note that this appears to be a cryptocurrency application.) I'd suggest that building everything from source code might not be a realistic solution to your security concerns. I don't know what your threat model is, but if it's something like, "Hackers and gangsters who scatter password-harvesting trojans across the globe and then shlurp up what they can," you might find that you get better security by generating your keys on a computer that never communicates with the outside world. Your concerns are (1) that the random numbers from which your keys have been corrupted to make them predictable, or (2) that malicious software will send your keys to the bad guys. Isolating the key-generation machine takes care of #2. If you have Python code for generating keys, something as simple as XORing a fixed value of your choice with its random numbers will take care of #1. I admit that using an isolated machine introduces a lot of inconveniences, but I bet it compares favorably with building everything from source. -- To email me, substitute nowhere->runbox, invalid->com. -- https://mail.python.org/mailman/listinfo/python-list

On my laptop, the program takes about 2.1 seconds with python 2.7 and 1.6 seconds with python 3.6. So the difference is 0.5 seconds overall or about 500 µs per execution. strace shows that python 2.7 explicitely closes all unneeded file descriptors below 1024 (even though most of them aren't actually open) in the child before execing bash, python 3 doesn't do that. I can see no other obvious difference. So that's ~ 1020 extra system calls. If this is indeed the only difference, that's about 500 ns per system call. That sounds plausible. hp -- _ | Peter J.

Groovy to Python Converter ?
In my new project, I am supposed to bring the current test cases, all written in Groovy, to a Python base. We are talking about several thousand test cases that have accumulated over the last years. Since the test cases are also to be extended towards API gateway testing, and since we work with Python requests here, we want and need to convert everything. But here is the question, which I could not answer even after an intensive search: Is there a converter that can convert Groovy based test cases to Python? An example of how the tests are structured. They are pure web tests that ask for links and other questions with just one click. Actually, it's absolutely simple, but not suitable for us for broad-based tests, even in the direction of expansion. -- https://mail.python.org/mailman/listinfo/python-list
