Answer by М.Б. for How to use a dot "." to access members of dictionary?

I've created a solution that should be able to handle (almost) every list/dict/tuple/object's attribute accessing using dot notation, or regular (first level) access:

def get(obj, key: str | int, default=None):"""    Try to get index, key or a property    for a given list, dict or object,    returns default on error    Args:        - obj (mixed): dict, list, object        - key (str):  either any key or dot accessor like: foo.bar.0    Returns:        - mixed | None"""    key = str(key)    keys = [key]    if '.' in key:        keys = key.split('.')    val = obj    for k in keys:        if not k:            continue        try:            if isinstance(val, list):                val = val[k]            elif isinstance(val, dict):                val = val.get(k, default)            else:                val = getattr(val, k, default)        except (IndexError, KeyError, AttributeError, TypeError, ValueError) as e:            if 'list indices must be integers or slices, not str' in str(e):                try:                    k = int(k)                    val = val[k]                except (ValueError, KeyError, IndexError):                    val = default            else:                return default    return val
