allow list or index

# Sometimes I make functions that can either allow an object or a list of objects.
# To do this I check if an input is an object and, if so, wrap it in a list.
# Here's a simple way to do that.

def _isArrayLike(obj):
    return hasattr(obj, '__iter__') and hasattr(obj, '__len__')
    
objs = objs if _isArrayLike(objs) else [objs]

#Another option is to do the opposite check:
if isinstance(obj, ObjType):
    obj = [obj]
