Problem extracting data from json format to csv using BeautifulSoup 3

I am trying to export Data from json format in CSV but getting no results. below is the code

import requests
from bs4 import BeautifulSoup
import json
import re

url = "https://www.daraz.pk/catalog/?q=dell&_keyori=ss&from=input&spm=a2a0e.home.search.go.35e34937qjElRf"



page = requests.get(url)

print(page.status_code)
print(page.text)
soup = BeautifulSoup(page.text, 'html.parser')
print(soup.prettify())

alpha = soup.find_all('script',{'type':'application/ld+json'})
jsonObj =`json.loads(alpha[1].text)`

for item in jsonObj['itemListElement']:
    name = item['name']
    price = item['offers']['price']
    currency = item['offers']['priceCurrency']
    availability = item['offers']['availability'].split('/')[-1]
    availability = [s for s in re.split("([A-Z][^A-Z]*)", availability) if s]
    availability = ' '.join(availability)

    print('Availability: %s  Price: %0.2f %s   Name: %s' %(availability,float(price), currency,name))

Here is the code I am trying to export Data in CSV but not getting results in CSV

Create a file to write to, add headers row

outfile = open('products.csv','w', newline='')
writer = csv.writer(outfile)
writer.writerow(["name", "offers", "price", "priceCurrency", "availability" ])
outfile.close()
alpha = soup.find_all('script',{'type':'application/ld+json'})

jsonObj = json.loads(alpha[1].text)

for item in jsonObj['itemListElement']:
    name = item['name']
    price = item['offers']['price']
    currency = item['offers']['priceCurrency']
    availability = item['offers']['availability'].split('/')[-1]
    availability = [s for s in re.split("([A-Z][^A-Z]*)", availability) if s]
    availability = ' '.join(availability)

you get not result because not writing the CSV in the loop

outfile = open('products.csv','w', newline='')
writer = csv.writer(outfile)
writer.writerow(["name", "type", "price", "priceCurrency", "availability" ])

alpha = soup.find_all('script',{'type':'application/ld+json'})

jsonObj = json.loads(alpha[1].text)

for item in jsonObj['itemListElement']:
    name = item['name']
    type = item['@type']
    price = item['offers']['price']
    currency = item['offers']['priceCurrency']
    availability = item['offers']['availability'].split('/')[-1]
    # forgot this?
    writer.writerow([name, type, price, currency, availability ])

# and close the CSV here
outfile.close()

I personally am a fan of Pandas to write a csv. Some might say its extensive. But it works.

import requests
from bs4 import BeautifulSoup
import json
import re
import pandas as pd

url = "https://www.daraz.pk/catalog/?q=dell&_keyori=ss&from=input&spm=a2a0e.home.search.go.35e34937qjElRf"



page = requests.get(url)

#print(page.status_code)
#print(page.text)
soup = BeautifulSoup(page.text, 'html.parser')
#(soup.prettify())

alpha = soup.find_all('script',{'type':'application/ld+json'})
jsonObj = json.loads(alpha[1].text)


results = pd.DataFrame()
for item in jsonObj['itemListElement']:
    name = item['name']
    price = item['offers']['price']
    currency = item['offers']['priceCurrency']
    availability = item['offers']['availability'].split('/')[-1]
    availability = [s for s in re.split("([A-Z][^A-Z]*)", availability) if s]
    availability = ' '.join(availability)

    row = [name,price,currency,availability]
    temp_df = pd.DataFrame([row], columns = ['name','price','currency','availability'])

    results = results.append(temp_df)

results.to_csv('products.csv', index=False)
