Question

到目前为止，我有这个。我打开了数据文件，我能够从数据中创建一个列表，并正确地从列表中打印出我需要的数据。它出现在python中就好了。但是当我尝试将其写入txt文件时，它全部显示在1行上。不知道该怎么做，它在新文本文件中分为2列。

# open file
data = open("BigCoCompanyData.dat", "r")
data.readline()

# skip header and print number of employees
n = eval(data.readline())
print(n)


# read in employee information
longest = 0
# save phone list in text file
phoneFile = open("PhoneList.txt", "w")


for i in range(n):
    lineI = data.readline().split(",")
    nameLength = len(lineI[1])+len(lineI[2])
    if nameLength > longest:
       longest = nameLength
       longest = longest + 5

    print((lineI[2].title()+", "+lineI[1].title()).ljust(longest) + ("("+lineI[-2][0:3]+")"+lineI[-2][3:6]+"-"+lineI[-2][6:10]).rjust(14))


    phoneFile.write((lineI[2].title()+", "+lineI[1].title()).ljust(longest) + ("("+lineI[-2][0:3]+")"+lineI[-2][3:6]+"-"+lineI[-2][6:10]).rjust(14))


data.close()

# close the file
phoneFile.close()

Answer 1

phoneFile.write(...)只是简单地写出你给它的那一行。每次你给出一行时，它都会将它附加到前一行，除非你用\n结束你的行。

phoneFile.write((lineI[2].title()+", "+lineI[1].title()).ljust(longest) + 
                ("("+lineI[-2][0:3]+")"+lineI[-2][3:6]+"-"+lineI[-2][6:10]).rjust(14)+'\n')
