Currently, if you input data, for example: 1, 1, 2, 2, 3 - it will come out like this: I would like it to just group the data if they have the same value in column2 and for this example, just show 2 : 2, meaning 2 of the numbers inserted were both inserted twice, so we will just count that. The second sort accesses each object only once to extract its count value, and then it performs a simple numerical sort which is highly optimized. Congratulations on reading to the end of this tutorial! are immutable in Python. If you need to use the get() method on each dictionary in a list, use a for Type: String to AttributeValue object map.
