mass editing for keys in a dictionary

[james_027]

hi,

How could I transform something like this

dict_1 = {'customer_id':1, 'item_id':3, amount:100}

into

dict_2 = {'customer':1, 'item':3, amount:100}

thanks
james

into

dict_2 = {'customer':1, 'item':3, amount:100}

A one liner would be :

dict_2 = dict([(k.split('_')[0], v) for (k,v) in dict_1.iteritems()])

It would split the keys by '_' and use first part of split as the new key !

You must be aware be careful in cases where there are keys like
'customer_1' , 'customer_2', ...

Cheers,
