如何索引类信息
如何索引类信息
提问于 2022-01-02 03:26:28
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，并通过索引和数据类型检索它。在所有这些转换之后，我有n个有数据的列表。
下面是来自txt文件的示例数据：
Date Time Latit(N) Long(E) Depth(km) MD ML Mw Region Method
---------- -------- -------- ------- ---------- ------------ ----------- -------
2021.12.18 22:27:57 36.2620 28.9352 10.5 -.- 3.1 3.2 AKDENIZ Quick
2021.12.18 21:53:20 35.0258 25.7753 5.0 -.- 2.7 -.- GIRIT ADASI ACIKLARI (AKDENIZ) Quick

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]

#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regex之后的数据在循环内部的“部件”中的样子：

事先非常感谢。

只需将parts列表的第一项发送给您的类，并删除构造函数中的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)页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
