Convert Tuple To List In A Dictionary

I have a dictionary like this: a= {1982: [(1,2,3,4)], 1542: [(4,5,6,7), (4,6,5,7)]} and I want to change the all the tuples (1,2,3,4),(4,5,6,7),(4,6,5,7) to lists,

Solution 1:

As far as I understand you want to convert each tuple in a list. You can do this using a dictionary comprehension:

{k: [list(ti) for ti in v] for k, v in a.items()}

will give

{1542: [[4, 5, 6, 7], [4, 6, 5, 7]], 1982: [[1, 2, 3, 4]]}

Is that what you are after?

Solution 2:

In-place:

for key, value in a.items():
    for i, t in enumerate(value):
        value[i]= list(t)

New objects:

{key: [list(t) for t in value] for key, value in a.items()}

Solution 3:

You can use "tupleo" library

from tupleo import tupleo.

val = tupleo.tupleToList(a[1542]).

print(val) [[4,5,6,7], [4,6,5,7]]

tupleo gives you full depth level conversion of tuple to list. and it have functionality to convert tuple to dict also based on index.
