[FIXED] Scrapy Extract value of a tag

Issue

I am doing my scrapy code where I have to extract data from website https://lemkus.com/collections/maylee/products/hannah-green-cord-pants?variant=43116172181756

Now Output should be like if item is out of stock only then show out_of_stock='True' along with size and otherwise dont show out_of_stock

Sample JSON output:

 "skus": [
  {
    "currency": "ZAR",
    "out_of_stock": true,
    "price": 850.00,
    "size": "8"
  },
  {
    "currency": "ZAR",
    "price": 850.00,
    "size": "10"
  },
  {
    "currency": "ZAR",
    "out_of_stock": true,
    "price": 850.00,
    "size": "12"
  },
  {
    "currency": "ZAR",
    "price": 850.00,
    "size": "14"
  }

The HTML Cde of website is:

        <fieldset class="fieldset-var  unavailable-product" data-var-id="43116172181756">
          
          <input class="js-variant-radio" name="id" type="radio" id="variant-1" value="43116172181756" data-inventory-qty="0">
          <label for="variant-1">8</label>
        </fieldset>  
    
        <fieldset class="fieldset-var variant-active " data-var-id="43116172214524">
          
          <input class="js-variant-radio" name="id" type="radio" id="variant-2" value="43116172214524" data-inventory-qty="1">
          <label for="variant-2">10</label>
        </fieldset>  
    
        <fieldset class="fieldset-var  unavailable-product" data-var-id="43116172247292">
          
          <input class="js-variant-radio" name="id" type="radio" id="variant-3" value="43116172247292" data-inventory-qty="0">
          <label for="variant-3">12</label>
        </fieldset>  
    
        <fieldset class="fieldset-var  " data-var-id="43116172280060">
          
          <input class="js-variant-radio" name="id" type="radio" id="variant-4" value="43116172280060" data-inventory-qty="1">
          <label for="variant-4">14</label>
        </fieldset>  
    
  

OK, So in the HTML Code above,see where the tag "data-inventory-qty" is equal to zero and in some fields its greater than 0 I want to do is if data-inventory-qty="0", Show out_of_stock='True' otherwise don't show out of stock

I have logic for extracting currency,price and size. I just need the out_of_stock by extracting the value of data-inventory-qty or using another attribute that might work.

A part of the code for out_of_stock I have done until now is

items=response.xpath('//div//form//div//fieldset//input[@data-inventory-qty])'.getall()

I need Like there are 4 sizes in the above code so make a list of 4 data. if data-inventory-qty is 0 with first item then append 'True' in the list otherwise append '' in the list.

So list for above HTML should be like ['','True','','True']

Solution

Something like this?

lst = response.xpath('//input[@class="js-variant-radio"]/@inventory-qty').getall()
result = [True if not int(i) else '' for i in lst]
print(result)

OUTPUT

[True, '', True, '']
