Python：如果文件名用逗号分隔，并且在不同的行上，如何从文件中读取名称？

Question

我需要修改当前读取文件的代码，该文件的用户名在单独的行中。如果名称用逗号分隔并且在单独的行上，则需要读取文件

我需要修改的当前代码是：

inFileName = input("Enter the file name with people's names: ")
outFileName = input("Enter the file name to write user names to: ")

inFile = open(inFileName, "r")
outFile = open(outFileName, "w")

namesSeq = inFile.readlines()

for name in namesSeq:
    splitName = name.rstrip().split (",")

    firstName = splitName[0]
    lastName = splitName [1]

    userName = firstName[:0] + lastName[:7]
    userName = userName.lower()

    print (userName, file=outFile)

inFile.close()
outFile.close()

我需要修改它以使用此文件：

Earl Anthony,Pete Weber, Mark Roth, Mike Aulby, Norm Duke
Tori Romeo, Jeri Edwards, Lynda Barnes, Nikki Gianulias, Cara Honeychurch

看起来像这样：

anthony
weber
roth
aulby
duke
romeo
edwards
barnes
gianuli
honeych

您可以使用re模块的split()函数来分隔inFile的所有名称。然后，您可以在split()操作产生的列表上循环，将每个用户名写入outFile

inFile = open(inFileName)
outFile = open(outFileName, 'w')

data = in_file.read()
for name in re.split(',|\n', data):
    print(name.split()[-1].lower()[:7], file=outFile)

inFile.close()
outFile.close()
