Question

I have a dictionary which has value as a list.

dictionary = { 
               'C1' : [10,20,30] 
               'C2' : [20,30,40]
             }

Let’s say I want to increment all the values in list of C1 by 10, how do I do it?

dictionary.get('C1') gives me the list but how do i update it?

Answer 1

>>> dictionary = {'C1' : [10,20,30],'C2' : [20,30,40]}
>>> dictionary['C1'] = [x+1 for x in dictionary['C1']]
>>> dictionary
{'C2': [20, 30, 40], 'C1': [11, 21, 31]}
