python - 使用类而不是列表 python

Question

我有以下代码:

#!/usr/bin/python
# -*- coding: utf-8 -*-

import sys import re

companies = {}
for line in open('/home/ibrahim/Desktop/Test.list'):
    company, founding_year, number_of_employee = line.split(',')
    number, name = company.split(")")
    companies[name] = [name, founding_year, number_of_employee]
    print "Company: %s" % company

CompanyIndex = raw_input('\n<Choose a company you want to know more about.>\n\n<Insert a companyspecific-number and press "Enter" .>\n')

if CompanyIndex in companies:
    name, founding_year, number_of_employee = companies[CompanyIndex]
    print 'The companys name is: ',name,'\nThe founding year is: ', founding_year,'\nThe amount of employees is: ', number_of_employee
else:
    print"Your input is wrong."

该程序从如下所示的文本文件中读取一些信息:

(1)Chef,1956,10
(2)Fisher,1995,20
(3)Gardener,1998,50

我的目标是获得一个类，我可以在其中保存有关公司名称、成立年份和员 worker 数的信息，而不是使用还包含列表的字典。

我看了几个教程，但我真的不知道该怎么做。这个“ self ”是什么 __init__ 和 __del__ 做的等等，这真的很令人困惑。我该怎么做？

Answer 1

你可以这样做:

class Company(object):

    def __init__(self, name, founding_year, number_of_employee):
        self.name = name
        self.founding_year = founding_year
        self.number_of_employee = number_of_employee

之后，您可以通过编写 company = Company('Chef', 1956, 10) 创建一个 Company 对象。
