JSON Python reading/writing to a json file issue

Code:

import json

numbers = [2, 3, 5, 7, 11, 13]
letters = ["a", "b", "c", "d"]
filename = 'numbers.json'

with open(filename, 'w') as f_obj:
    json.dump(numbers, f_obj)
    json.dump(letters, f_obj)


with open(filename) as f_obj:
    numbers = json.load(f_obj)
    letters = json.load(f_obj)

print(numbers)
print(letters)

I would like to be able to read multiple lists which I have added to a json file and set them as separate lists which can be used later.

I don't mind having to adding a new line between each list in the json file and then reading it in line format.

why not store them inside a global dictionary ? 

import json

numbers = [2, 3, 5, 7, 11, 13]
letters = ["a", "b", "c", "d"]
filename = 'numbers.json'

val={'numbers': numbers, 'letters':letters}

with open(filename, 'w') as f_obj:
    json.dump(val, f_obj)


with open(filename) as f_obj:
    val = json.load(f_obj)
    numbers = val['numbers']
    letters = val['letters']

print(numbers)
print(letters)
