Question

所以基本上我正在尝试制作一个程序，从一个文件中获取名称的格式＆＃34; Smith，Robert＆＃34; 并制作一个看起来像＆＃34; RobeSmit，Smith，Robert，RobertSmith，（随机生成的密码）＆＃34;的输出。我已经完成所有工作，但它只能做一个名字，我需要它做的文件中有多少例如：Smith，Robert Boe，Joe

这就是我所拥有的：

import random

def readFile():
    f_input = open("myFile.txt", "r")
    string = f_input.read()
    f_input.close
    return string

def firstFour(string):
    lastNameFour, firstNameFour = string.split(",")
    userName = (str(firstNameFour[1:5]) + str(lastNameFour[0:4]))
    return userName

def nameArrangement(string):
    lastName, firstName = string.split(",")
    names = (str(lastName)) + "," + str(firstName) + "," + str(firstName) + str(lastName)
    return names

def passwordGen():
    alphabet = "abcdefghijkmnopqrstuvwxyz23456789ABCDEFGHJKLMNPQRSTUVWXYZ!@#$%^&*()-=_+\][|}{;?/.,<>"
    length = 7
    password = " "
    for i in range (length):
        nextChr = random.randrange(len(alphabet))
        password = password + alphabet[nextChr]
    return password

def putItTogether(userName, names, password):
    output = userName + ", " + names + ", " + password
    print (output)

def main():
    string = readFile()
    userName = firstFour(string)
    names = nameArrangement(string)
    character = passwordGen()
    putItTogether(userName, names, character)

if __name__ == '__main__':
    main()`

任何帮助将不胜感激。谢谢！

Answer 1

你main函数应该是：

def main():
    with open("myFile.txt", "r") as f:
        for string in f:
            userName = firstFour(string)
            names = nameArrangement(string)
            character = passwordGen()
            putItTogether(userName, names, character)

让我们检查您的代码并将阅读线嵌入其中。

更改readFile以返回所有行：

def readFile():
    # with is used when a resource is only needed in a certain context. 
    # we'll use it for opening files so they close automatically.
    with open("myFile.txt", "r") as f:
        return f.readlines()

写saveFile以在文件中存储已处理的行：

def writefile(lines):
    with open("myFile.txt", "w") as f:
        f.writelines(lines)

编写processLine以包装单行处理，返回结果（不需要putItTogether）：

def processLine(line):   
    userName = firstFour(string)
    names = nameArrangement(string)
    character = passwordGen()
    return userName + ", " + names + ", " + password

现在使用map将处理应用于所有行（也可以执行list comprehension），然后将其写回：

def main()
    writeFile(map(processLine, readFile()))

提示：这不是很普遍，想一想从值中抽象动作的方法。例如，readFile应该读取文件而不是特定文件。它应该定义为def readFile(filename)。

祝你好运。

如何在python中将文件拆分为单独的行？
