Question

我正在尝试编写一个代码（在python上），该代码将读取包含产品列表的文件，每个产品的GTIN-8代码，每个产品的描述，库存和价格。

到目前为止，我设法阅读了顶线，打印出了详细信息，但我不确定如何阅读下一行。任何帮助？请尽量保持简单：）

我的男人Doroskevic的代码：

#csv is imported to read/write to the file
import csv

#Each Product is printed alongside it's GTIN-8 code and Price
print("~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~")
print("~ Welcome to Toms bits and bobs ~")
print("Pencil,          12346554, £0.40")
print("50 Staples,      12346882, £1.00")
print("50 Paper Clips,  12346875, £1.20")
print("Large Eraser,    12346844, £1.50")
print("100 A4 Sheets,   12346868, £2.00")
print("100 A3 Sheets,   12346837, £2.50")
print("25 Byro Pens,    12346820, £2.20")
print("Handwriting Pen, 12346899, £5.50")
print("50 Split Pins,   12346813, £0.60")
print("Office Chair,    12346912, £25.00")
print("~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~")

#The file is opened and the user inputs the code for the product they
#wish to find.
file = open("Product_list.csv", "r")
purchase = input(print("Please enter the GTIN-8 code of the product you wish to purchase e.g 12346554"))
line = file.readline()
data = line.split(",")
if purchase == "12346554":
    while(line):
        print ("Product: ", data[0])
        print ("GTIN-8 code: ", data[1])
        print ("Stock: ", data[2])
        print ("Description: ", data[3])
        print ("Price: ", data[4])
        line = file.readline()
        break
if purchase == "12346882":
    while(line):
        print ("Product: ", data[0])
        print ("GTIN-8 code: ", data[1])
        print ("Stock: ", data[2])
        print ("Description: ", data[3])
        print ("Price: ", data[4])
        line = file.readline()
        break

file.close()

示例：

path = 'c:/users/-e/my documents/text.txt' with open(path, 'r') as file: data = file.readlines() for line in data: print(line, end='')

<强>输出：

Are all the good times dead and gone? Come and go and come and go (come and come and go) I got a lot of friends who are stars But some are just black holes By Fall out boy - 27

函数.readlines()会将文件中的所有行读入list结构。这将允许根据需要进行进一步的操作。
