# parsl.channels.LocalChannel¶

class parsl.channels.LocalChannel(userhome='.', envs={}, script_dir=None, **kwargs)[source]

This is not even really a channel, since opening a local shell is not heavy and done so infrequently that they do not need a persistent channel

__init__(userhome='.', envs={}, script_dir=None, **kwargs)[source]
