I am invoking a cross chaincode from the set method of my chaindode and it properly records the information I send. However, when I invoke the cross chaincode from the get method, then the data is not recorded.

To verify that it was not an implementation failure, I copied the function that goes in the get method into the set method as a test and it responded correctly, so I suspect that it is the fact of invoking the same cross-chaincode from another method.

Part of the set method code that works properly including the function copied from get method:

I have three arrays:

Each array has a "key" and a "value" for every element, for example

I am extremely new to Python and have only just started learning so any advice and tips would be fantastic. Im trying to make a program that allows the user to convert text into Binary.

The process for this would be Text > Hexidecimal > Binary.

Im doing this mainly to challenge myself and to get a better understanding of how Python works, so excuse the terrible code.

The issue im facing is that when the user inputs a Hexidecimal such as "41" the program should check the dictionary for the associated value, which would be "01000001". But instead i get this error message:

i'm building a web application that send some information to an API (API Gateway of AWS) and it receive back an image and some informations (strings) about that image. The strings and the image are generated by a lambda function (AWS service) written in python.

The idea is to have a simple html page where I enter information, press a button and after processing in the cloud I am shown an image and some information. The management of the json received by the API gateway is done in javascript.

I already have the code for the management of the html page, it is already tested and it works, I show it for completeness:

I use hardcoded ec-kyes for testing my application. There is example for ecdsa:

Basically pandas object is applying to entire data frame not individually that is why it is going to else condition. we need to apply on each rows

I got proper output while applying on one row frame. While applying entire data frame I got the error No keys on each rows, Basically some rows of res have None only those rows are expected to be No keys

So, I made some high speed opencv camera detection code, got it running on my debian labtop, and bought some 720p60 chinese usb cam. All worked well. However I wanted to make it run on my TinkerBoard S (tinkerOS - debian).

Here the camera simply refused to get detected, as my lsusb output hinted (also tried guvcview & cheese, none worked):
