Read all the contents in ini file into dictionary with Python

Normally, I code as follows for getting a particular item in a variable as follows

try:
    config = ConfigParser.ConfigParser()
    config.read(self.iniPathName)
except ConfigParser.MissingSectionHeaderError, e:
    raise WrongIniFormatError(`e`)

try:
    self.makeDB = config.get("DB","makeDB")
except ConfigParser.NoOptionError:
    self.makeDB = 0

Is there any way to read all the contents in a python dictionary?

For example

[A]
x=1
y=2
z=3
[B]
x=1
y=2
z开发者_Python百科=3

is written into

val["A"]["x"] = 1
...
val["B"]["z"] = 3

I suggest subclassing ConfigParser.ConfigParser (or SafeConfigParser, &c) to safely access the "protected" attributes (names starting with single underscore -- "private" would be names starting with two underscores, not to be accessed even in subclasses...):

import ConfigParser

class MyParser(ConfigParser.ConfigParser):

    def as_dict(self):
        d = dict(self._sections)
        for k in d:
            d[k] = dict(self._defaults, **d[k])
            d[k].pop('__name__', None)
        return d

This emulates the usual logic of config parsers, and is guaranteed to work in all versions of Python where there's a ConfigParser.py module (up to 2.7, which is the last of the 2.* series -- knowing that there will be no future Python 2.any versions is how compatibility can be guaranteed;-).

If you need to support future Python 3.* versions (up to 3.1 and probably the soon forthcoming 3.2 it should be fine, just renaming the module to all-lowercase configparser instead of course) it may need some attention/tweaks a few years down the road, but I wouldn't expect anything major.

I managed to get an answer, but I expect there should be a better one.

dictionary = {}
for section in config.sections():
    dictionary[section] = {}
    for option in config.options(section):
        dictionary[section][option] = config.get(section, option)

---

I know that this question was asked 5 years ago, but today I've made this dict comprehension thingy:

parser = ConfigParser()
parser.read(filename)
confdict = {section: dict(parser.items(section)) for section in parser.sections()}

The instance data for ConfigParser is stored internally as a nested dict. Instead of recreating it, you could just copy it.

>>> import ConfigParser
>>> p = ConfigParser.ConfigParser()
>>> p.read("sample_config.ini")
['sample_config.ini']
>>> p.__dict__
{'_defaults': {}, '_sections': {'A': {'y': '2', '__name__': 'A', 'z': '3', 'x': '1'}, 'B':         {'y': '2', '__name__': 'B', 'z': '3', 'x': '1'}}, '_dict': <type 'dict'>}
>>> d = p.__dict__['_sections'].copy()
>>> d
{'A': {'y': '2', '__name__': 'A', 'z': '3', 'x': '1'}, 'B': {'y': '2', '__name__': 'B', 'z': '3', 'x': '1'}}

Edit:

Alex Martelli's solution is cleaner, more robust, and prettier. While this was the accepted answer, I'd suggest using his approach instead. See his comment to this solution for more info.

How to parse ini file in py?

import ConfigParser
config = ConfigParser.ConfigParser()
config.read('/var/tmp/test.ini')
print config.get('DEFAULT', 'network')

Where test.ini file contain:

[DEFAULT]
network=shutup
others=talk

One more thing to take care is, ConfigParser converts the key values to lowercase hence in case you are converting the config entries to a dictionary cross check your requirements. I faced a problem because of this. For me I was having camel-case keys hence, had to change some amount of code when I started using the dictionary instead of files. ConfigParser.get() method internally converts the key to lower-case.

suppose file: config.properties contains the following:

• k =v
• k2= v2
• k3= v3

python code:

def read_config_file(file_path):
        with open(file=file_path, mode='r') as fs:
            return {k.strip(): v.strip() for i in [l for l in fs.readlines() if l.strip() != ''] for k, v in [i.split('=')]}


print('file as dic: ', read_config_file('config.properties'))

def ConfigSectionMap(section):
dict1 = {}
options = Config.options(section)
for option in options:
    try:
        dict1[option] = Config.get(section, option)
        if dict1[option] == -1:
            DebugPrint("skip: %s" % option)
    except:
        print("exception on %s!" % option)
        dict1[option] = None
return dict1
