QUESTION
So I have this dash app where I want to display a png image based on the user's input. It works, but the problem is every time the user makes a selection the image is shown on top of the previous image. I want to somehow clear the previous image so it only shows the most recently selected image.
In app.layout I have:
ANSWER
Answered 2021-Jun-14 at 23:36To update existing image you should use html.Img(...) instead of html.Div(..., children=[]) in app.layout, and update component_property='src' instead of component_property='children'
Many tools can save image/file in file-like object created in memory with io.BytesIO()
Example for matplotlib
QUESTION
I will explain the goal in more detail, The point of the script is to check (product code)values in column A on a supplier website, if the product is available, the loop checks the next value.
If the product is not on the site, a JSON PUT request is sent to a different sales website that sets the inventory level at 0.
The issue is how to assign the value in column B of the same CSV file to the PUT request
CSV file
...ANSWER
Answered 2021-Jun-14 at 13:45From scrapy’s documentation Passing additional data to callback functions, you basically want to pass the code to the data callback in Request’s cb_kwargs argument,
To get all codes, you could iterate on (COL-A, COL-B) pairs, not simply on COL-A values. Here we return the 2d numpy array, thus the list of rows, where each row is the COL-A, COL-B pair:

This is impossible with wget --spider. wget manual says that when you use --spider
When invoked with this option, Wget will behave as a Web spider, which means that it will not download the pages, just check that they are there. For example, you can use Wget to check your bookmarks:
wget --spider --force-html -i bookmarks.htmlThis feature needs much more work for Wget to get close to the functionality of real web spiders.
wget with --spider option does fetch response headers, which you can print following way

Answered 2021-Jun-12 at 00:19With @url http://www.amazon.com/s?field-keywords=selfish+gene I get also error 503.
Probably it is very old example - it uses http but modern pages use https - and amazone could rebuild page and now it has better system to detect spamers/hackers/bots and block them.
If I use @url http://toscrape.com/ then I don't get error 503 but I still get other error FAILED because it needs some code in parse()

QUESTION
Please excuse the use of var, it is part of the challenge and is intended to help me learn about closure. Currently, the code gives all 100 h3's the same sentence. I've tried moving the randomName, randomWeapon, and randomLocation variables into the addEvent function. When I do this I assign the same h3 a new sentence on every click. I'm guessing I need to use .call or .apply, but I am new to functions, and internet tutorials just aren't getting me there.
...ANSWER
Answered 2021-Jun-11 at 20:59The problem is that your addEvent bind the click hander on the body and not on the h3. And the second is that you do e.preventDefault when you have not defined e (you should set it on the click handler,not the addEvent function) which causes an error and stops the execution.
If you had fixed the e issue, you would see that when you click on an h3 you get all 100 alerts.

I have a bash script that checks if the CHECKURL variable has a response or not. If the url is not valid or doesn't exist the script immediately exits and echo a message "NOT VALID URL"
I have one problem in which the url https://valid-url-sample.com is a valid url however my IP is rejected on the load balancer because it only respond on 443 request from specific IP's. The result is the script stays running until I it requires me to control+c. I would like the script to handle this kind of condition and echoes "VALID BUT NOT REACHABLE", I also added timeout on the wget command but still no luck. any thoughts on how to handle this?

Answered 2021-Jun-07 at 15:35I found a solution to my problem. In fact, just as I suspected, there was a missing directory to my PYTHONPATH. It was the directory that contained the gtts package.
Solution: If you have the same problem,
- Find the package
I looked at that post
- Add it to sys.path (which will also add it to PYTHONPATH)
Add this code at the top of your script (in my case, the pipelines.py):
