Recursive version of ‘reload’

by

I’ve run up against the same issue, and you inspired me to actually solve the problem.

from types import ModuleType

try:
    from importlib import reload  # Python 3.4+
except ImportError:
    # Needed for Python 3.0-3.3; harmless in Python 2.7 where imp.reload is just an
    # alias for the builtin reload.
    from imp import reload

def rreload(module):
    """Recursively reload modules."""
    reload(module)
    for attribute_name in dir(module):
        attribute = getattr(module, attribute_name)
        if type(attribute) is ModuleType:
            rreload(attribute)

Or, if you are using IPython, just use dreload or pass --deep-reload on startup.
