从txt调用来定义一些东西...... Python

Question

所以我有一个名为Person的类,基本上有构造函数名称,id,年龄,位置,目的地,我想要做的是当我想创建一个新人时,我希望它从txt文件打开.

例如,这是我的Person类(在Module,People中)

class Person :
    def __init__(self, name, ID, age, location, destination):
        self.name = name
        self.ID = ID
        self.age = age
        self.location = location
        self.destination = destination

    def introduce_myself(self):
        print("Hi, my name is " + self.name + " , my ID number is " + str(self.ID) + " I am " + str(self.age) + " years old")

import People

Fred = People.Person("Fred", 12323, 13, "New York", "Ithaca")

Fred.introduce_myself()

所以基本上,而不是我必须手动键入该初始化器"fred,12232"等.我希望它从已经写入所有内容的txt文件中读取.

这就是txt文件中的内容

[Name, ID, Age, Location, Destination]
[Rohan, 111111, 28, Ithaca, New Caanan]
[Oat, 111112, 20, Ithaca, New York City]
[Darius, 111113, 12, Los Angeles, Ithaca]
[Nick, 111114, 26, New Caanan, Ithaca]
[Andrew, 111115, 46, Los Angeles, Ithaca]
[James, 111116, 34, New Caanan, Ithaca]
[Jennifer, 111117, 56, Los Angeles, New Caanan]
[Angela, 111118, 22, New York City, Los Angeles]
[Arista, 111119, 66, New Caanan, Los Angeles]

Answer 1

instances = {}         #use a dictionary to store the instances

#open the file using `with` statement, it'll automatically close the
#file for you
with open('abc') as f:
    next(f)                 #skip header
    for line in f:          #now iterate over the file line by line        
        data = line.strip('[]').split(', ')  #strip [] first and then split at ', '
        #for first line it'll return:
            #['Rohan', '111111', '28', 'Ithaca', 'New Caanan']  , a list object

        #Now we can use the first item of this list as the key 
        #and store the instance in the instances dict 
        #Note that if the names are not always unique then it's better to use ID as the
        #key for the dict, i.e instances[data[1]] = Person(*data)
        instances[data[0]] = Person(*data)  # *data  unpacks the data list into Person

#Example: call Rohan's introduce_myself
instances['Rohan'].introduce_myself() 

输出：

Hi, my name is Rohan , my ID number is 111111 I am 28 years old
