Python: 如果名称由逗号分隔并在不同的行中，如何从文件中读取名称？

Question

我需要修改当前读取用户名分行的文件的代码。如果名称以逗号分隔并在不同的行中，它需要读取文件。

我目前需要修改的代码是：

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

Answer 1

尝试以下操作：

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")

for line in inFile:
    names = line.split(",")
    for name in names:
        userName = name.split()[1].lower()[:8]
        print(userName, file=outFile)

inFile.close()
outFile.close()

Answer 2

您可以使用re模块的split()功能来分隔您inFile的所有名称。然后你可以遍历 split() 操作的结果列表，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()
