Translate PYTHON code to VB .NET

[erty33]

Hello,

Does someone could help me translating the following PYTHON code to VB .NET ?

Thank you very much

Eh, I could, but it's a non-trivial conversion.

The argument parsing alone would be 20-30 lines of VB minimum, unless I find a NuGet package to do the same thing as 'argparse'. I guess in hindsight I could do it in 8-10 lines but it won't do exactly the same thing in all scenarios if I cut that corner.

The next bit makes a REST request and does a handful of things with the JSON it returns. The request/parse structure is going to be anything from 10-100 lines of code depending on how you count and if you feel like doing it "right".

The most complex branch is 'userdetails'. It generates a pair of hashes, then uses that data to make two other REST requests. That's all said and done another 20-30 lines.

I think it'd take me between 1-2 hours to translate it as a console application, and more like 5-10 if you wanted a GUI. Then, if I wanted to teach you something, I'd spend 2-3 more hours minimum on the material. 3-12 hours is an awful lot to ask of a stranger.

If you have the Python and it works, why bother? What motivates translating it to VB .NET? Have you tried translating it yourself? What parts did you get stuck on?

People often say "can you help with this" when what they actually mean is "can you do this for me". Trying to convert code from one language to another by simple replacement of "commands" is a good way to end up with unusable code, just as doing the same with spoken/written languages can end up producing gibberish. The best way to go is to analyse the functionality provided by the existing code and then determine the best way to provide that functionality in the target language. We can certainly help with specific issues along the way but if you're looking for someone to volunteer their time to just write the code for you then I expect that you'll be disappointed. Are you perhaps a VB developer who found some PHP code on the web that reportedly does what they want and you want to avoid having to understand PHP?

Python. If it was PHP the type names would be like "ArgemuntPraser" or more idiomatic "preg_parser()". And the whole script wouldn't work without this at the top:

$six = 7
$seven = 6

PHP is like Perl only if you dropped Perl on its head a few times as a baby.

Python. If it was PHP...

Oops! Just started doing some PHP work at the office and had it in mind. They both begin with P so what's the difference?

You can manage to do some converting yourself, I have done this with JS to VB and the other way around.

You start by what does the code do, and not just it adds 1+1, litterally breaking it down function by function, and then converting it to the equivlent of vb.net.

jmc, doesn't mean any harm when he says, that when you ask for help you mean do it for you, but its true we are all guilty of it at some point even myself included.

You can convert it by asking these questions:

1: What does it do at the end result?

2: What is used to complete the operation?

3: Can this be done simplier.


I can answer almost all of these questions, but it wouldn't be 110% right, and only a guess.

The first thing is you are printing information about a server, this could be anything from just pinging to finding out how old a page is.

What us used here is a If Then, Else operation in vb.net it looks like this:

If X = Y then

Y = X 
Elseif Y = X then

X = Y

Else

console.write("Error X = Y returned false")

End If

For the web requests, its very similar to what you have you simply create a new web request, you can find information on web requests in this article: https://docs.microsoft.com/en-us/dot...brequest-class


Yes, it is in C#, but as stated in another thread C# can be converted with a free converter online
