QUESTION
I am working on a page with Brython, and one thing I would like to do is load a JSON file on the same server, in the same directory.
How can I do that? open()? Something else?
Thanks,

I have a Python backend that generates public/private keys, generates a payload, then needs to get that payload signed by the client (ReactJS or pure JS), which is later verified.
The implementation in Python looks like this:

Answered 2021-Dec-18 at 11:56CryptoJS only supports symmetric encryption and therefore not ECDSA. WebCrypto supports ECDSA, but not secp256k1.
WebCrypto has the advantage that it is supported by all major browsers. Since you can use other curves according to your comment, I will describe a solution with a curve supported by WebCrypto.
Otherwise, sjcl would also be an alternative, a pure JavaScript library that supports ECDSA and especially secp256k1, s.here.
WebCrypto is a low level API that provides the functionality you need like key generation, key export and signing. Regarding ECDSA WebCrypto supports the curves P-256 (aka secp256r1), P-384 (aka secp384r1) and p-521 (aka secp521r1). In the following I use P-256.
The following JavaScript code generates a key pair for P-256, exports the public key in X.509/SPKI format, DER encoded (so it can be sent to the Python site), and signs a message:

QUESTION
i am trying to install the module requests but it is not working
...ANSWER
Answered 2021-Sep-06 at 19:36Something simple like import re probably works in your setup.
https://docs.python.org/3/library/re.html
But requests is not part of python's standard library.
You will want to arrange for its dependencies separately.
https://pypi.org/project/requests/
https://pypi.org/project/brython-pack
brython-pack packages your Python packages/files into a brython_modules.js.
QUESTION
I am currently trying to use Brython for the website I am making, but I cannot get the data from the user for my program.
I set up a box for the user to type in an ID...
...ANSWER
Answered 2021-Mar-08 at 16:04(Thanks to Hernán Alarcón for directing me to this.)
Because I used the GET request, which will append the parameters to the URL, Brython has an attribute query that searches for URL parameters.
Using the expression document.query['id'] will give 12345678 for the example URL. This yields the same results as the JavaScript code posted in the question.
Apparently I missed this page of documentation at Brython.
QUESTION
I have a piece of code that needs to execute on a webworker which needs to get feedback from something in the main thread (basically a get operation from a KVS). Unfortunately, I cannot use local storage because it is not accessible from a webworker. Is there any other way I can convey information from the main thread to the webworker such that when the webworker wants this piece of information, it can have it?
Another note is that I am using brython for everything, and I'm not sure if that prevents me from using traditional JavaScript solutions like IndexedDB. Guidance would be much appreciated.

you are appending your numbers to a list and essentially trying to print them out all at once, using a for iteration loop this can be avoided.
QUESTION
I am creating a web application using python with the brython.js library and for my application I need to import the bs4 library and the requests library but I don't know how.
Any idea?
...ANSWER
Answered 2021-Jan-26 at 20:48Like in standard Python, you can install modules or packages Python in your application by putting them in the root directory, or in directories with a file __init__.py.
Note: that modules must be encoded in utf-8; the encoding declaration at the top of the script is ignored.
For instance, the application can be made of the following files and directories:
QUESTION
In recent day I've doing a mini-project (Conway's Game of Life) with python.
I want to do the GUI for the browser, so I decided to use a library called brython, that allow me to use python in the client side (is an interpreter, transforming python code to js code).
The problem I am currently having is that I can't import classes from other file, with the import line.
The structure of folder and files is the next: Game
- Web
- Game
- _ _ init _ _.py
- Cell.py
- Game.py
- Game
- index.css
- index.html
- index.py
index.py is the file that will be execute when the page is charged. The same has this lines that generate the error (when I commented the error disappear but I can't use what I have to use, lol):
import Game.Game as Game
Game.py has a similar line that generate the same error too:
from Game.Cell import Cell
The console in the browser shows the next line: Failed to load resource: the server responded with a status of 404 (File not found)
And this too: Error 404 means that Python module Game was not found at url http://localhost:8000/Game/Web/Game.py
So, the problem is I'm not specifying well the URL, but I don't know how to solve it. Any help?
...ANSWER
Answered 2021-Jan-07 at 03:26You should also include the Web forlder to the import. Therefore, your import should be like this: import Web.Game.Game as Game and from Web.Game.Cell import Cell. Also, don't forget to add in your index.html for these imports to work.
QUESTION
Hi I am using Brython as a beginner. My requirement is to ping one IP address from the browser based application. I want to know whether it is possible in case of Brython. I have written a very small piece of code to achieve it.
index.html
...ANSWER
Answered 2020-Sep-18 at 06:17This is not possible from the browser. You can not execute an system calls from a browser. Brython is like a transpiler like Typescript.
Refer this link. As per this link "but anyway, for security reasons, it's not possible to execute a program in the command line such as ping from a browser, be it in Javascript or Brython."

Install brython
To install Brython locally, if you have a CPython distribution with pip :. then create a new directory and run. or by loading the latest version of the Brython zip file from the [releases page](https://github.com/brython-dev/brython/releases). In both cases, the distribution includes brython.js (the core Brython engine) and brython_stdlib.js (a bundle of all the files in the standard distribution). It also includes the page demo.html that shows a few examples of how you can interact with a web page using Python as the scripting language : create new elements, access and modify existing elements, create graphics, animations, send Ajax requests, etc.
