For further reading on checking if a key exists in a dictionary, go to the article: How to Check if a Key Exists in a Dictionary in Python. In Python, the list data structure stores elements in sequential order. Return proportions rather than frequencies. We will get the values as a list, and we can unpack the list directly as follows: Lets see what happens when we search for a ham and pineapple pizza: The key ham and pineapple does not exist in the dictionary, and therefore, we print the not found statement to the console.

How to handle missing value if imputation doesnt make sense, How do you get out of a corner when plotting yourself into a corner, Calculating probabilities from d6 dice pool (Degenesis rules for botches and triggers). 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. That's not entirely true, since your output shows a list containing dicts, which will still fail if you call .values() or keys() on it. Here I have three inputs with datetime.
