Accessing values in list inside dictionary when you don't know the count

Question

I have output in below form:

data = {ItemA: [123456, 123654], ItemB: [456789, 456987]}

To get the values, I can access them as data.ItemA[0], data.ItemA[1]

But how do you deal when you don't know how many values are there for ItemA in the list. How can I get all individual values of ItemA without knowing how many items will be in list beforehand.

Answer 1

You can just access the entire list and use it however you want:

data = {'ItemA': [123456, 123654], 'ItemB': [456789, 456987]}
my_list = data['ItemA']

my_list will then just be the entire list, and you can check its length, pull out specific items (like you were doing before), iterate through it etc.

Answer 2

So for that you need to iterate over dictionary and than from the key you get you need to iterate the list inside that.

data = {'ItemA': [123456, 123654], 'ItemB': [456789, 456987]}
for key in data:
    for items in data[key]:
        print(key ,':' , items)

Key will iterate over dictionary and contains 'ItemA' and 'ItemB'. Then from there yoū can iterate over that dictionary key and get list
