Is it possible to implement this in python and connect it to WordPress or write in pure html, or maybe someone will advise some kind of WordPress plugin or their own solution to the problem?

1) What exactly are you going to write in pure html? html is the markup language. Accordingly, you cannot implement any interaction logic on it.
2) If you decide to write in python, then continue the idea and use the Django framework. Further these csv files you import into a DB (mapping in a DB). For convenience, use an ORM. Next, implement the search (you can take elasticsearch and create the necessary indexes). Well, then the rest of the functionality of the site and the online store.
3) If you decide to do everything on WordPress, then the Woocommerce plugin (online store). Use CSV tables to create products from them. For example, the WP All Import + Woocommerce Addon plugin for importing products.
