ConfigParser - print config.sections() returns []

问题

I'm trying to use a ConfigParser module to parse an *.ini file. The problem is that when I try to print sections or whatever, it returns empty list [].

config.ini

[SERVER]
host=localhost
port=9999
max_clients=5
[REGULAR_EXPRESSIONS]
regular_expressions_file_path=commands/commands_dict

config.py

# -*- coding: utf-8 -*- 
import ConfigParser

config = ConfigParser.SafeConfigParser()
config.read("config.ini")
print config.sections()

[]

Do you know where is the problem?

EDIT: Here is a screen of my structure:

Your code works for me. Are you sure that your CWD points to the right directory with the right config.ini file in it?

$ cat config.ini
[SERVER]
host=localhost
port=9999
max_clients=5
[REGULAR_EXPRESSIONS]
regular_expressions_file_path=commands/commands_dict

I had the same issues and silly enough the problem was simply that the structre of my files was:

src_folder
          |db
              |database.ini
              |config.py

In config.py I had a function like this:

#!/usr/bin/python

from configparser import ConfigParser


def config(filename="database.ini", section="postgresql") :
    # create a parser
    parser = ConfigParser()

    if not parser.read(filename):
        raise Exception(f"Reading from File: {filename} seems to return and empty object")

    else:
        parser.read(filename)
    ...

Which would inevitably return

Exception: Reading from File: database.ini seems to return and empty object

Spot the issue?

It's in the path string I pass to the filename argument!

Given the structure it should be

"db/database.ini"

argh.

Had the same problem, and I could not figure out what was causing it, but in my case I typed:

config.read = ("file-name.ini")

And it should have been

config.read("file-name.ini")
