Extracting information from a file

[lokhtar]

Hello guys,

I have a directory with a lot of text files, I need to loop through them and extract a certain section from them. The Text files are formatted in a standard way, in this way:

ABC: this is a text
 
SECTION 2: this is more text
 
ANOTHER SECTION: blah blah blah. This is another section
 
SECTION 4:
SECTION 5:
* A list
* Another list. I need this
 
YET ANOTHER SECTION: A bunch. of sentences. exist here.
 
OTHER FINDINGS: None.
 
FINAL
THIS IS NOT IMPORTANT

What I need to do, is to extract the "section 5" portion of the text. I know the split method, but splitting the file by ":", and then further splitting by "*" - doesn't quite seem right:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

import glob   #list of all the text files path = "reports/*.txt"     file_id=0   #loop through files, one at a time for file_name in glob.glob(path):     file_id += 1           with open (file_name, 'rt') as myfile:         current_file = myfile.read()               section_list = current_file.split(':')     for list_section in section_list:         further_split = list_section.split('*')         for x in further_split:             print("An item in list :" + str(further_split))

Is there a more elegant/better way to get to what I need? What I am really after is that within the section that I care about, I want to loop through each of the subsections, which are delineated by "*" and work with those strings.

I would appreciate any help!

please attach a small test file

It won't let me upload files on this forum for some reason, so I uploaded it on the website: http://s000.tinyupload.com/download.php?...4983370453

You need 5 posts then you will be able to upload, so should be able to do so soon, same applies to editing your post.
I used your link this time.

I'll get back as soon as I get a chance to examine code.

This will get you started. I switched to pathlib (requires python 3.6 or newer) rather than Glob as it is OOP
and then just printer each line without modification.

You can add your parsing back in from here

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38

import os from pathlib import Path     def read_files():     # assure that starting path is script path     os.chdir(os.path.abspath(os.path.dirname(__file__)))       file_id = 0       #list of all the text files     scriptpath = Path('.')     reportpath = scriptpath / 'reports'     # print(f"working directory: {reportpath.resolve()}")       # Get list of text files     textfiles = [filename for filename in reportpath.iterdir() \         if filename.is_file() and filename.suffix == '.txt']       print()       for filename  in textfiles:     # #loop through files, one at a time     # for file_name in glob.glob(path):         file_id += 1                   with filename.open() as myfile:             for line in myfile:                 line = line.strip()                 print(f"{line}")         # section_list = current_file.split(':')         # for list_section in section_list:         #     further_split = list_section.split('*')         #     for x in further_split:         #         print("An item in list :" + str(further_split))   if __name__ == '__main__':     read_files()

output:

Output:
ABC: this is a text file.  I need to do stuff with it.

SECTION 2: this is more text

ANOTHER SECTION: blah blah blah. I have lots of information here.

SECTION 4:
SECTION 5:
* A list
* Another list. I need this

YET ANOTHER SECTION: A bunch. of sentences. exist here.
* Another list. I don't need this

OTHER FINDINGS: None.

FINAL
THIS IS NOT IMPORTANT

SECTION 6:
* A bunch. of sentences. exist here.

A example with one way to parse lines in SECTION 5.

1 2 3 4 5 6 7 8 9 10

flag = 1 with open('sample_file.txt') as f:     for line in f:         if line.startswith('SECTION 5:'):             flag = 0             #next(f) # Will skip first line in SECTION 5         if line.startswith('SECTION 6:'):             flag = 1         if not flag and not line.startswith('SECTION 5:'):            print(line.strip())

Output:
* A list
* Another list. I need this
