# Recipe 6.18. Automatically Initializing Instance Variables from _ _init_ _ Arguments

# Solution
# You can "factor out" the attribute-assignment task to an auxiliary function:
def set_attributes_from_dict(d):
    self = d.pop('self')
    for n, v in d.iteritems():
        setattr(self, n, v)

# Now, the typical boilerplate code for an _ _init_ _ method such as:

function httpdate2unixtimestamp(date,    array, time_string, timestamp) {
    # input: [02/Dec/2011:04:02:42 -0500]
    # output: 1322816562
    # date is argument
    # array, time_string, timestamp is local variable
    split(date, array, "[]/: []")
    if (array[3]=="Jan") month="01"
    else if (array[3]=="Feb") month="02"
    else if (array[3]=="Mar") month="03"
    else if (array[3]=="Apr") month="04"
