[Baypiggies] nested list to dict question

[Vikram K]

I have a nested list which looks something like this:

x = [['104', '4501919'], ['104', '237681091'], ['104', '7669477'],
['100528064', '315259111']]

I wish to convert this to a dict type which looks something like this:

y = {'104': ['4501919', '237681091', '7669477'], '100528064': ['315259111']}

Please help!

Thanks
Vikram
