### INI File Content Example

Source: https://github.com/pytest-dev/iniconfig/blob/main/README.rst

This is an example of an INI file structure that can be parsed by iniconfig. It includes sections, key-value pairs, comments, and multi-line values.

```ini
# content of example.ini
[section1] # comment
name1=value1  # comment
name1b=value1,value2  # comment

[section2]
name2=
    line1
    line2

```

### Basic iniconfig Usage

Source: https://github.com/pytest-dev/iniconfig/blob/main/README.rst

Demonstrates how to load an INI file and access its contents using the iniconfig module. Shows retrieving values, handling missing keys, and iterating through sections.

```python
>>> import iniconfig
>>> ini = iniconfig.IniConfig("example.ini")
>>> ini['section1']['name1'] # raises KeyError if not exists
'value1'
>>> ini.get('section1', 'name1b', [], lambda x: x.split(','))
['value1', 'value2']
>>> ini.get('section1', 'notexist', [], lambda x: x.split(','))
[]
>>> [x.name for x in list(ini)]
['section1', 'section2']
>>> list(list(ini)[0].items())
[('name1', 'value1'), ('name1b', 'value1,value2')]
>>> 'section1' in ini
True
>>> 'inexistendsection' in ini
False

```
