Option 1 - using a class:

def run(env, command, args):
    plugin = Plugin(env)
    # Check if the command is defined in the plugin
    if 'do_'+ command not in dir(plugin):
        return False
    # Call function
    getattr(plugin, 'do_'+ command)(args)

class Plugin(object):
    """docstring for Plugin"""
    def __init__(self, env):
        super(Plugin, self).__init__()
        self.env = env
        
    def do_cd(self, args):
        '''
        Command: cd - change directory
        '''
        print "do cd"

Option 2: without a class ---- incomplete

def run(env, command, args):
    plugin = Plugin(env)
    # Check if the command is defined in the plugin
    if 'do_'+ command not in dir(plugin):
        return False
    # Call function
    getattr(plugin, 'do_'+ command)(args)

def do_cd(env, args):
    '''
    Command: cd - change directory
    '''
    print "do cd"
