Python-將文本文件保持在一行嗎？

Question

我正在編寫一個以有序方式顯示產品列表的代碼，用戶可以輸入GTIN-8代碼並選擇他們希望“購買”的數量。 因此，當用戶輸入GTIN-8代碼時，FullLine應該是產品說明等，該說明位於產品列表中並顯示金額。 但是，該金額顯示在我不希望的新行上。 我嘗試將換行符放在產品列表之后，之前和之下，但不會停留在同一行上。 這是代碼：

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 are your purchases: \n")
Receipt.close()

print("Please enter the GTIN-8 Codes of the products you want and how many")
IfFinished=""
while IfFinished != "Yes":
    ProductsWanted=input("Please enter the GTIN-8 Code of the product: ")
    AmountOfProducts=input("How many do you want? ")

    with open("Productsfile.txt") as f:
        for line in f:
                if ProductsWanted in line:
                    FullLine=(line +"Amount: " +AmountOfProducts)
                    print(FullLine)
                    Receipt=open("ReceiptFile.txt","a")
                    Receipt.write(str(FullLine))
                    Receipt.close()

因此，在運行時，我得到了例如：

23456945, Thorntons Chocolate Box, £10.00
Amount: 2

但是我希望金額在同一行

Answer 1

使用rstrip方法，更改FullLine=(line +"Amount: " +AmountOfProducts)

到FullLine=(line.rstrip() +"Amount: " +AmountOfProducts)
