如何获得新线路

Question

如何在输出文件上打印新行？当我尝试用“/n”添加新行时，它只打印/n这就是我迄今为止所拥有的。`` inputFile = open("demofile1.txt", "r") outFile = open("ji    string = line.split(',')    go =(string)[3::]    bo = [float(i) for i in go]    total = sum(bo)    pine = ("%8.2f"%total)    name = string[2] + "," + " " + string[1]    kale = (string[0] + " " + name + " " + "/n")    se)当前结果8 53 Baul A999999

您需要使用\n，而不是/n。所以这一行：

kale = (string[0] + " " + name + " " + "/n")

应该：

kale = (string[0] + " " + name + " " + "\n")

另外，请考虑使用str格式化程序，所以所有这些行：

go =(string)[3::]

bo = [float(i) for i in go]

total = sum(bo)

pine = ("%8.2f"%total)

name = string[2] + "," + " " + string[1]

kale = (string[0] + " " + name + " " + "/n")

str1 = ''.join(kale)

str2 = ''.join(pine)

outFile.write(str1 + " " + str2 + " ")

会变成：

outFile.write("{} {} {:8.2f}\n".format(string[0], string[2] + ", " + string[1], sum(bo))
