python，通过类运行来自单独文本文件的每一行

Question

我想要一些帮助，弄清楚如何通过一个类从文本文件运行单独的行，这是我到目前为止的工作：

class Employee:
   'Class for all employees'
   empCount = 0

   def __init__(self, payNo, salary, job, mName, fName, sName):
      self.payNo = payNo
      self.salary = salary
      self.job = job
      self.mName = mName
      self.fName = fName
      self.sName = sName
      Employee.empCount += 1

   def displayCount(self):
     print ("Total Employee %d" % Employee.empCount)

   def displayEmployee(self):
      print ('{:<2s}{:<1}{:<13s}{:<15s}{:<7d}{:16s}{:>5s}{:<6d}'.format(self.sName,", ", self.mName, self.fName, self.payNo, self.job,"£",self.salary))
      ##print ('{:20s}{:20s}{:20s}'.format(self.sName,self.mName,self.fName))

"This would create first object of Employee class"
emp1 = Employee(12345, 2000, "Consultant", "Bartholomew", "Homer", "Simpson")
"This would create second object of Employee class"
emp2 = Employee(12346, 5000, "conultant in jobs","daniel", "matt", "li")
emp1.displayEmployee()
emp2.displayEmployee()
print ("Total Employee(s) %d" % Employee.empCount)

with open("emps.txt") as fileobject:
    for line in fileobject:
      print (line)

任何帮助将不胜感激，谢谢

有人可能会说这更“ Pythonic”

[('{4}, {5} {0} {2} ${1}'.format(*emp)) for emp in 
                 ((12345, 2000, "Consultant", "Bartholomew", "Homer", "Simpson"), 
                  (12346, 5000, "conultant in jobs","daniel", "matt", "li"))]

>>> ['Homer, Simpson 12345 Consultant $2000', 
     'matt, li 12346 conultant in jobs $5000']

如果此列表来自csv文件，则您可以：

import csv
with open('in_file.csv') as in_file:
    for line in csv.reader(in_file):
        print '{4}, {5} {0} {2} ${1}'.format(*line)
