def find_mod(module_name):
"""
Find module `module_name` on sys.path, and return the path to module `module_name`.
- If `module_name` refers to a module directory, then return path to __init__ file.
- If `module_name` is a directory without an __init__file, return None.
- If module is missing or does not have a `.py` or `.pyw` extension, return None.
- Note that we are not interested in running bytecode.
- Otherwise, return the fill path of the module.
Parameters
----------
module_name : str
Returns
-------
module_path : str
Path to module `module_name`, its __init__.py, or None,
depending on above conditions.
