Remove empty arrays, objects or null elements from a JSON value

remove_empty_elements.py

def remove_empty_elements(d):
    """recursively remove empty lists, empty dicts, or None elements from a dictionary"""

    def empty(x):
        return x is None or x == {} or x == []

    if not isinstance(d, (dict, list)):
        return d
    elif isinstance(d, list):
        return [v for v in (remove_empty_elements(v) for v in d) if not empty(v)]
    else:
        return {k: v for k, v in ((k, remove_empty_elements(v)) for k, v in d.items()) if not empty(v)}

Thank you 🙏

thanks for you useful solution

Thank you , elegant solution !

thank you!

thank you !!!
I needed a function to remove all keys with (values == "") from a very large, very nested JSON, and changing a little bit the function empty() worked flawlessly.

def empty(x):
    return x is None or x == {} or x == [] or x == ""

thanks sm worked marvellously
