Can anyone help me how to extract particular word from the text() from the Xpath expression
I'm currently scrapping the names of the coins from Website:https://coinmarketcap.com/currencies/bitcoin/

(//h1[@class='priceHeading']/text())[1]
which has 'Bitcoin Price' I just need the first word 'Bitcoin' ignoring the rest.
Don't mind my mistakes, I'm a newbie here :)
...ANSWER
Answered 2022-Apr-15 at 12:05Well, it kind of depends upon what you can rely on, and which version of XPath you are using. Whether a space is sufficient, or if you would want some more sophisticated tokenization is largely dependent on the data and your requirements.
With XPath 1.0 and later, you can use substring-before() a space
QUESTION
I have the below code that fetches data from Coinmarketcap api and sends me a telegram message when parameters are met. When I fetch 100 coins then the code works fine. But when I fetch 5000 coins the code is very slow. The schedule time with refresh api is not the time that I have code.
Can someone see why the code is slow with fetching data from the api with 5000 coins?
A good answer is insert httpx / asyncio in the code. (answer Pawel Rubin (thanks). Does someone know how i can insert asyncio into the code?
...ANSWER
Answered 2022-Apr-01 at 13:50The code is making requests sequentially for every element in parsed['data'].
Consider running your code asynchronously with some HTTP client that supports asyncio, for example httpx, and use asyncio.gather to run your requests concurrently.
Consider the following example which makes 50 GET requests to google.com using requests and using httpx. Note that the async solution is significantly faster.

QUESTION
I'm a total beginner with Python/Django and trying to understand why this isn't working. I have a function that contains a for loop, doing some logic and then updating a model. but when I have more than 1 item in the loop I get a UNIQUE constraint failed: app_token.token_name error.
So I think I'm misunderstanding how the loop is working?
function
...ANSWER
Answered 2022-Jan-22 at 10:31I believe that by calling Token.objects.update() you actually end up trying to update all Token objects. Since token_name has to be unique, and you are giving it the same name as another Token object it throws that error. Since you are already in a for loop, you can simply update the token that is currently being processed.
My suggestion would be to use this code instead:

Answered 2022-Jan-02 at 00:11There are two issues with your code:
- This:
if check_name == coins_list:will always return false, sincecheck_nameis a string andcoins_listis a list. You wantif check_name in coins_list:. baseurlisn't defined in the code snippet. Change it tourl.
Perform both these changes, and you should have a nonempty output in your text file. The URLs in this file appear to be well-formed.

(modified after the advice from the comments)
What I'm trying to do: Web scraping to get all 100 cryptocurrency names from this website.
Problem: The selector I used doesn't select all crypto names on the page. Only some of them are selected.
In that webpage, there are 100 rows, and each row has one cryptocurrency name. So 100 names in total.
If I use this selector tr td a[href*="/currencies/"][href$="/"]:not([href$="/markets/"]),
It finds all 100 elements on the page, and I can get each crypto's URL from these 100 elements. (there are 100 cryptocurrencies on one page)
one sample of the selected 100 elements:
