from ebaysdk.trading import Connection as trading
import pandas as pd

api = trading(
appid="real appid used",

,escape_xml=True)

if True:
ebay_df = pd.read_csv('output_ebay.csv')
for index, row in ebay_df.iterrows():
ebay_item_no = row['itemid']
ebay_title = row['title']
ebay_description = row['description']

    try:
        api.execute('ReviseFixedPriceItem', {'item': {'itemID': ebay_item_no, 'title': ebay_title,
                                                      'description': "<![CDATA[{0}]]>".format(ebay_description)}})
        sleep(0.2)
        response_r = api.response_content()
        print(response_r)
        print(ebay_item_no)
    except:
        print('Error in Item Number ',ebay_item_no)
    else:
        print('Success')
