【问题描述】：
我正在制作一个以有序方式显示产品列表的代码，用户可以输入 GTIN-8 代码并选择他们希望“购买”的数量。因此，当用户输入 GTIN-8 代码时，FullLine 应该是产品列表中的产品描述等并显示数量。但是，金额出现在我不想要的新行上。我尝试将换行符放在产品列表之后、之前和之下，但它不会保持在同一行。 代码如下：
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()
所以在跑步时，我得到，例如：
23456945, Thorntons Chocolate Box, £10.00
Amount: 2
但我希望金额在同一行

尝试使用
line.strip()返回一个新字符串，不带任何前导或尾随空格，包括换行符。
