Python - Keeping text file in one line? -


i'm making code shows product list in ordered way, , user can input gtin-8 code , select amount wish 'purchase'. when user inputs gtin-8 code, fullline should product description etc in product list , show amount. however, amount appearing on new line don't want. i've tried putting newline after product list, before , under it, won't stay on same line. here code:

nl="\n" products=open("productsfile.txt","w") products.write(nl+"23456945, thorntons chocolate box, £10.00") products.write(nl+"12376988, cadburys easter egg, £15.00") products.write(nl+"76543111, galaxy bar, £1.00") products.write(nl+"92674769, cadury oreo bar, £1.00") products.write(nl+"43125999, thorntons continental box, £12.00") products.close()  products=open("productsfile.txt","r") print(products.read())  receipt=open("receiptfile.txt","w") receipt.write("here purchases: \n") receipt.close()  print("please enter gtin-8 codes of products want , how many") iffinished="" while iffinished != "yes":     productswanted=input("please enter gtin-8 code of product: ")     amountofproducts=input("how many want? ")      open("productsfile.txt") f:         line in f:                 if productswanted in line:                     fullline=(line +"amount: " +amountofproducts)                     print(fullline)                     receipt=open("receiptfile.txt","a")                     receipt.write(str(fullline))                     receipt.close()

so when running, get, e.g.:

23456945, thorntons chocolate box, £10.00 amount: 2

however want amount on same line

using rstrip method, change fullline=(line +"amount: " +amountofproducts)

to fullline=(line.rstrip() +"amount: " +amountofproducts)
