# Python RLCompleter Module

The `rlcompleter` module defines a completion function suitable for the `readline` module by completing valid Python identifiers and keywords.

## Importing the Module

```python
import rlcompleter
import readline
```

## Basic Usage

To use `rlcompleter`, you typically just need to import it and configure `readline` to use its completer function.

```python
import rlcompleter
import readline

readline.parse_and_bind("tab: complete")
```

This enables tab completion for Python identifiers in the interactive interpreter.

## The `Completer` Class

The module provides a `Completer` class.

```python
completer = rlcompleter.Completer()
```

You can pass a dictionary (namespace) to the constructor to restrict completion to that namespace.

```python
my_locals = {'hello': 'world', 'foo': 'bar'}
completer = rlcompleter.Completer(my_locals)

print(completer.complete('he', 0)) # Output: 'hello'
```
