attrdict.py

[Skaperen]

i added an __init__() method which handles zero or more arguments of dict/attrdict or list/tuple of zero or more key:value 2-sequence pairs.

class attrdict(dict):
    '''Class that is like a dictionary with items usable like attributes.

#---------------------------------------------------------------
# purpose       class that is a dictionary with items usable
#               like attributes
#
# init usage    object = attrdict(dictionary)
#               object = attrdict(dictionary,key=value...)
#               object = attrdict(key=value...)
#
# attr usage    object.name
#
# dict usage    object[key]
#
# note          attribute usage is like string keys that are
#               limited to what can be a valid identifier.
