on windows you just type in the name of the venv file, then \Scripts\activate as long as you are in the project folder. Example: PS D:\Projects\Scrapy> .venv\Scripts\activate

The issue we faced in part 6 was that the values added to the attributes of our `BookItem` instance in the `parse_book_page` method were being passed as `tuples` instead of `strings`. Removing commas at the end of the values should resolve this issue. Once we fix this problem, everything should work perfectly without needing to modify the `process_item` method.

Finally someone understands what we reaally need and it is published 9 months ago, how did i miss it, i hope this time i will have a Python adventure by not wasting 100's of hours and wasted it for nothing. If it happens again i will curse python and its devolopers. So many changing things, thing can be outdated in seconds and don't know from where to fix it etc. etc. I will hopefully update this adventure.

1:34:58 instead of using a lot of if statement use mapping. for example: # saving the rating of the book as integer ratings = {"One": 1, "Two": 2, "Three": 3, "Four": 4, "Five": 5} rating = adapter.get("rating") if rating: adapter["rating"] = ratings[rating] This is not only faster but it also looks clean.

If someone has a similar problem he can just index into the url like this: 'str(item["description"][0])' (instead of the code provided which is this: 'str(item["description"]') in the excute function in the process_item function.

Sorry, I just want to know how to let scrapeops knows mysql info like (hostname, port, user, password, database) if I don't want to show it in my code directly. I've saved mysql password in .env file at local, and I don't want to push .env file onto github which brings the result that scrapeops can't connect to mysql when schedule run. I also try to add mysql info as key:value arguements when scheduling, but it's not work. Can someone help me to solve it.... :(

Hello folks! I'm currently at the part 5 and here is my question. If there is an answer for this in the following parts of this course please let me know. When we export the results into a file, the first book at the file is not "A light in the Attic". Also that is same for me and probably all of us. Is that a problem or what is it? The number of items scraped is 1k, so the scraped item number is matching with the numbers of total books we want to scrape. To be honest I'm wondering how item not coming to output without the order in the site.
