下面是文本文件“ info.txt”的结构。从此文件中，我需要提取ID和描述（可以正确提取ID和描述信息的任何方法）。该文件中大约有500个ID和描述的实例。一个ID代表一个标题和一个描述，如文本文件中所示。
我不确定的第一部分是是否将ID和描述信息存储在2个列表中。如果我使用列表，那么我将能够使用“描述”列表来标记每个描述（请记住，该列表中将有500个描述）。

我想在这里实现一些目的，一个是创建一个所有单词的单字词汇，其格式为word_string：integer_index。二）创建一个文本文件，其中每一行对应一个描述。该行将从ID（保留＃）开始。每行的其余部分是对应描述的稀疏表示形式，其形式为word_index：word_freq，以逗号分隔。
我想这就是为什么我认为将ID和Description信息存储在列表中会是理想的原因。这样，ID列表中的索引0将是＃22579462，描述列表中的索引0将是对应的描述文本。
预先感谢

您可以一次读入文件，然后使用regex findall对其进行解析。 “ rslt”列表包含（ID，描述）元组：
with open("info.txt") as ff:
rslt= re.findall(r"(?sm)^\s*ID:\s*#(\d+)\s*$.*?^Description:(.*?)(?:\s*(?=^ID: #)|\Z)",ff.read())
（？sm）-> m：多行模式，s：dot（。）也匹配新行；
^ \ s * ID：\ s *＃（\ d +）->匹配行的开头，空格和“ ID：＃”模式，然后匹配数字，将其分组（请参阅括号） ）;
\ s * $->在数字后，该行只能包含空格；
。*？^描述：->跳过标题，并匹配“描述：”模式；
（。？）（？：\ s （？= ^ ID：＃）| \ Z）->（。*？）获得描述 文本（分组）到下一个以“ ID：＃”开头或字符串\ Z结束的块。

如评论中所述，您的数据似乎正在引导您使用字典。首先，创建一个忽略空行的函数。可以在here中找到空白函数，这是一个很好的解释。然后，调用该函数以逐行导入txt并将其保存在字典中。最后，将生成一个数据帧，其中索引是您的ID。
import pandas as pd
file=r"C:\***\***\info.txt".replace('\\', '/')
d={}
def nonblank_lines(f):#ingore blank lines
for l in f:
line = l.rstrip()
if line:
yield line
#importing txt line by line into a dictionary
with open(file) as my_file:
for line in nonblank_lines(my_file):
key = line.split(': ')[0]
if key not in d:#if key not in dictionary then create empty
d[key] = []
d[key].append(line.split(': ')[1])#populate the keys
#drop unwanted keys
my_keys=['Description','ID','Title']
for key, value in d.items():
if key not in my_keys:
del(d[key])
#Create a df with ID as index and the rest of data in columns
df=pd.DataFrame(data={your_key:d[your_key] for your_key in ['Description','Title']},index=d.get('ID'),columns=['Description','Title'])
df.to_csv(r'path\filename.txt',sep=',', index=True, header=True)#save your df
