What to do if collections.defaultdict is not available?

Solaris python 2.4.3:

from collections import defaultdict

does not exist..

Please advise what could be an alternative to use multi-level dictionaries:

dictOut['1']['exec'] = 'shell1.sh'
dictOut['1']['onfailure'] = 'continue'
...
dictOut['2']['exec'] = 'shell2.sh'
dictOut['2']['onfailure'] = stop'

many thanks applom

I just wonder why not to use single level dict with tuple as hash key?

As an alternative to setdefault, if you want extra level of dictionary goodness, try

class MultiDict(dict):
    def __getitem__(self, item):
        if item not in self.iterkeys():
            self[item] = MultiDict()

        return super(MultiDict, self).__getitem__(item)

setdefault?

dictOut.setdefault('1', {})['exec'] = 'shell1.sh'
