在尝试将数据从 txt 文件存储到 python 类时，我遇到了一个问题，我不知道如何在类中存储信息并按索引和数据类型检索它。在所有转换之后，我有 n 个包含数据的列表。

这是来自 txt 文件的示例数据：

Date       Time      Latit(N)  Long(E)   Depth(km)     MD   ML   Mw    Region                                            Method
---------- --------  --------  -------   ----------    ------------    -----------                                       -------

这是课程：

import re

class txt_data:
    def __init__(self, result):
       
       for i in result:
           
            self.date = result[i][0]
            self.time = result[i][1]
            self.latit = result[i][2]
            self.long = result[i][3]
            self.depth = result[i][4]
            self.md = result[i][5]
            self.ml = result[i][6]
            self.mw = result[i][7]
            self.region = result[i][8]
            self.method = result[i][9]
    
  
    def date(self):
        return self._date

  
    def time(self):
        return self._time

  
    def latit(self):
        return self._latit

  
    def long(self):
        return self._long

  
    def depth(self):
        return self._depth

  
    def md(self):
        return self._md

  
    def ml(self):
        return self._ml

  
    def mw(self):
        return self._mw

  
    def region(self):
        return self._region

  
    def method(self):
        return self._method     

#regex 
ptn = re.compile(
    r"^([\d.]+)\s+([\d:]+)\s+([\d.]+)\s+([\d.]+)\s+([\d.]+)\s+([\d.]+|-\.-)\s+([\d.]+|-\.-)\s+([\d.]+|-\.-)\s+([\w\s()-]+?)\s+([\w]+[\d]+\s+\([^)]*\)|\s+[a-zA-Z]+)$")

result = []
with open("input.txt") as fic:
    fic.readline()  # header
    fic.readline()  # dash
    for line in fic:
        parts = ptn.findall(line.rstrip())
        result.append(txt_data)

下面是正则表达式之后的数据在循环内的“部分”中的样子：

问题是如何修复我的类以将数据添加到其中并使用索引进行检索。我尝试在课堂内循环，但无法正常工作。

非常感谢您。

只需将parts 列表的第一项发送到您的类，并在构造函数中删除for 循环：

import re

class txt_data:
    def __init__(self, result):

        self.date = result[0]
        self.time = result[1]
        self.latit = result[2]
        self.long = result[3]
        self.depth = result[4]
        self.md = result[5]
        self.ml = result[6]
        self.mw = result[7]
        self.region = result[8]
        self.method = result[9]    

#regex 
ptn = re.compile(
    r"^([\d.]+)\s+([\d:]+)\s+([\d.]+)\s+([\d.]+)\s+([\d.]+)\s+([\d.]+|-\.-)\s+([\d.]+|-\.-)\s+([\d.]+|-\.-)\s+([\w\s()-]+?)\s+([\w]+[\d]+\s+\([^)]*\)|\s+[a-zA-Z]+)$")

result = []
with open("input.txt") as fic:
    fic.readline()  # header
    fic.readline()  # dash
    for line in fic:
        parts = ptn.findall(line.rstrip())
        result.append(txt_data(parts[0]))
        
print(result[3].region)  # PINARBASI-CAMARDI (NIGDE)
