kandi X-RAY | spla Summary
SPLA provides specialized functions for linear algebra computations with a C++ and C interface, which are inspired by requirements in computational material science codes. Currently, SPLA provides functions for distributed matrix multiplications with specific matrix distributions, which cannot be used directly with a ScaLAPACK interface. All computations can optionally utilize GPUs through CUDA or ROCm, where matrices can be located either in host or device memory.

QUESTION
I would like to refractor invalid URLs to valid ones if possible, otherwise just return an empty String.
Here are 5 examples:
Call me by your name https://www.amazon.de/dp/B07B58SGWP/ref=cm_sw_r_cp_api_fabc_iCJ6Fb0QVVW8Y?_encoding=UTF8&psc=1

So I tought about it and I would need a function that strips down a String to the actual URL only ( first three examples ) but also refractor the ones with letters that can't be in a valid URL. I am mostly struggling with the second one. I don't quite get why these can't be regactored in a valid Swift URL even if they can be opened in a normal Webbrowser...
Any help is appreciated!

Answered 2021-Jan-14 at 22:18A possible solution, is to try to find an URL. Let's separate each "subelement", then test each subelement, and try to percent escape invalid characters.

I am scraping an Amazon product page and using Beautiful Soup to find the product name and price. For some reason, the "title" variable will return sometimes and other times I will get the error, "'NoneType' object has no attribute 'get_text'"
