Question

我正在制作一个以有序方式显示产品清单的代码，用户可以输入GTIN-8代码并选择他们希望“购买”的金额。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金额。但是，金额出现在我不想要的新行上。我已经尝试将换行符放在产品列表之后，在它之前和之下，但它不会保持在同一行。这是代码：

 cat list.txt | ./calc.sh 1000 23

所以在跑步的时候，我得到了，例如：

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()

但是我希望金额在同一行

Answer 1

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

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

Python - 将文本文件保存在一行中？
