Issue in removing extra characters from string python

Question

I have a string given as:

text = """'select \"ORDER_ID\",\r\n    \"LINE_ID\",\r\n    \"PRODUCT_ID\",\r\n    \"CUSTOMER_ID\",\r\n    \"PAYMENT_METHOD\",\r\n    \"STATUS\",\r\n    \"DATETIME_ORDER_PLACED\",\r\n    \"DATETIME_ORDER_SHIPPED\",\r\n    \"ORDER_QTY\",\r\n    \"ORDER_AMOUNT\",\r\n    \"ORDER_COST\",\r\n    \"ORDER_VAT\",\r\n    \"SHIPPING_COSR\"\r\nfrom \"DEMO\".\"DEMO\".\"ORDERS\""

I am trying to clean this using below code:

text = text.replace("\", '').replace('"', '')

I got the following result:

'select ORDER_ID,rn    LINE_ID,rn    PRODUCT_ID,rn    CUSTOMER_ID,rn    PAYMENT_METHOD,rn    STATUS,rn    DATETIME_ORDER_PLACED,rn    DATETIME_ORDER_SHIPPED,rn    ORDER_QTY,rn    ORDER_AMOUNT,rn    ORDER_COST,rn    ORDER_VAT,rn    SHIPPING_COSRrnfrom DEMO.DEMO.ORDERS

I cannot figure out why I am getting rn with every word. How I can get rid of this ? I even tried using text = text.strip('rn') but it is not working.

Answer 1

You will have to replace \r\n first. You can do that by

text = text.replace("\r\n", '').replace("\", '').replace('"', '')

Like this:

text = query_text = 'select \"ORDER_ID\",\r\n    \"LINE_ID\",\r\n    \"PRODUCT_ID\",\r\n    \"CUSTOMER_ID\",\r\n    \"PAYMENT_METHOD\",\r\n    \"STATUS\",\r\n    \"DATETIME_ORDER_PLACED\",\r\n    \"DATETIME_ORDER_SHIPPED\",\r\n    \"ORDER_QTY\",\r\n    \"ORDER_AMOUNT\",\r\n    \"ORDER_COST\",\r\n    \"ORDER_VAT\",\r\n    \"SHIPPING_COSR\"\r\nfrom \"DEMO\".\"DEMO\".\"ORDERS\"'
print(text.replace('\"', '"').replace('\r', "r").replace("\n", "n"))

Output:

select "ORDER_ID",
    "LINE_ID",
    "PRODUCT_ID",
    "CUSTOMER_ID",
    "PAYMENT_METHOD",
    "STATUS",
    "DATETIME_ORDER_PLACED",
    "DATETIME_ORDER_SHIPPED",
    "ORDER_QTY",
    "ORDER_AMOUNT",
    "ORDER_COST",
    "ORDER_VAT",
    "SHIPPING_COSR"
from "DEMO"."DEMO"."ORDERS"

You get these kinds of strings for example when you call the repr function on a string:

print(repr('''new line:
'single quotes',"double quotes"'''))

Output:

'new line:n'single quotes',"double quotes"'

Escaping is commonly used on the web.
