How do you get rid of the gaps in the CSV file?
<p>when I run my programme, in the blank CSV file, there seems to be an one line gap between each product. How do you get rid of that gap? (shown in the first picture)</p>

<p><a href="https://i.stack.imgur.com/76KYP.png" rel="nofollow noreferrer">This is what happens when I fully run my code</a></p>

<p><a href="https://i.stack.imgur.com/Z25vU.png" rel="nofollow noreferrer">This is my original CSV file that contains all the product information. Row A is the GTIN-8 code, row B is the product name, C is the current stock level, D is the re-order stock level, and E is the target stock level (Just to clarify)</a></p>

<p>This is my code:</p>

<pre><code>import csv
redo='yes'

receipt=open('receipt.txt', 'wt')

stock=open('Stock_.csv', 'rt')
stock_read=csv.reader(stock)

blank_csv=open('Blank_csv_.csv', 'wt')
blank_csv_write=csv.writer(blank_csv)


clothes=(input('\nPlease enter the GTIN-8 code of what you want to purchase: '))
quantity=int(input('\nPlease enter the amount of this product you want to buy: '))

for row in stock_read:
    GTIN=row[0]
    product=row[1]
    current=row[2]
    re_order=row[3]
    target=row[4]

    if clothes==GTIN:
        current=int(current)-quantity
    blank_csv_write.writerows([[GTIN,product,current,re_order,target]])

stock.close()
blank_csv.close()

reorder_receipt=open('receipt.txt', 'wt')

blank_csv2=open('Blank_csv_.csv', 'rt')
blank_csv_read2=csv.reader(blank_csv2)

stock_check=input('Press \"ENTER\" if you want to check the current stock leavels: ')

if stock_check=='':
    for row in blank_csv_read2:
        for field in row:

            GTIN=row[0] 
            product=row[1]
            current=int(row[2])
            re_order=int(row[3])
            target=int(row[4])
            if current&lt;=re_order:
                re_stock=target-current
                reorder_receipt.write(GTIN+' '+product+' '+str(current)+' '+str(re_order)+' '+str(target)+' '+str(re_stock)+'\n')

blank_csv2.close()
reorder_receipt.close()
</code></pre>

<p>Thank you in advance!!!!</p>
