optparse | Simple command line arguments parser for BASH | Command Line Interface library

I followed this document and I can get what I want. The most importance thing is that the command does not copy the generated files into the pyhton 3.9.4 folder automatically. You have to copy them manually.

1) first download the project under this link and then unpack the file.

Run these under cmd:

I think, it's kinda "interface" realization. It's equal to:

Using argparse (optparse is deprecated), options can have a types (int, str, ...). But you can use json.loads or ast.literal_eval as type to parse the JSON string:

Ok, seems I have solved it - without knowing the specific reason of the failure:

I just stepped back from sleekxmpp version 1.3.3 to version 1.3.1. And now it workes as before.

... and just for the record - just found out that sleekXMPP is deprecated - see here: https://github.com/fritzy/SleekXMPP

This example is intended for Bloomberg's BPIPE product and as such includes the necessary authorization code. For this example, if you're connecting to the Desktop API (typically localhost:8194) you would want to pass an auth parameter of "none". Note that this example is for the mktdata snapshot functionality which isn't supported by Desktop API.

You state you're trying to troubleshoot on behalf of other users, presumably traders using BPIPE under their credentials. In this case you would need to create an Identity object to represent that user.

This would be done thusly:

If you restructure your parser such that run_and_hide, lie_down_and_sing, &c. are subcommands with their own subparsers, you will indeed be able to use the same flag with a different meaning between those subparsers.

Is it possible to change your structure to incorporate function arguments? If you are calling it from another script it would make it easier.

First off welcome to SO.

So a few things that may help you out. People don't usually use python's HTTPServer unless you're wanting to control the lower part of http request and response. If you want to use a easy to use/setup http server flask is a great option as it will handle parsing POST data as well as saving files when they come through.

Q1. Is there a better way to identity files?

A1. This depends. During an http request to upload a file http standard is to upload the file name and extension along with the file's bytes. If you only upload bytes then most http servers will just ignore it and return an error. So if you send the name and extension along with the bytes than you know what kind of data it is and how to store it.

Also base64 is an encoding. So the only way to know if the encoding is good or not (malformed/dropped bytes) is to actually try and decode it and then catch any errors when it finds them. There is no way of asking it if it's a valid encoding without it actually trying to decode the data.

Q2. Can you blindly handle errors in python?

A2. Yes you can though it is discouraged to do so.

There is at least one problem: the recfile file is opened before starting the loop, and closed inside the loop. That means that beginning from the second iteration, you will try to write on a closed file and get an exception.

How to avoid: with open(...) as ...: blocks are great because not only they guarantee proper closure in case of errors, but they also ensure a correct bloc structure in your program.

BTW, count should also be reset to 0 inside the loop, and the closer to the loop the better for future readers and maintainers of the code
