changing values of a dictionary to a list

Question

I have the following code snippet where am assigning values to dictionary..currently the dictionary values are getting printed as normal values..i want to them to convert to a list,how do i change the "database[data]=value" line to achieve this?

database={} ....... database[data]=value //assigning value to a dictionary print database ............... Expected output:- internal_dep = {'313115': ['313113'],'213114': ['213103'] } Current output:- internal_dep = {'313115': '313113','213114': '213103' }

Thanks

Your question is hard to understand. The answerers have interpreted it in at least 2 different ways. — jpaugh

you can try:

database[data]=[value]

If you only want to print it this way, you can try:

print({k:[v] for k, v in database.items()})

A list cannot (easily) be used as a dictionary in Python—although Lisp does represent dictionaries this way. However, you can get at either the values or the keys and convert them to a list like so:

print list(database.values())

or

print list(database.keys())
