I am attempting to employ C++17 fold expressions and the C++14 indices trick to flatten an arbitrary input consisting of tuples and non-tuples.
While trying to serialize a named value tuple to JSON string, it loses the names assigned to itemsI am expecting the serialized value as
I have a variable defined like thisI expect drum to be a tuple of tuple. (i.e. ((a, b, c))).And I have another variable defined like this
I am trying to remove all strings from a list of tuplesI have started to try and find a solution:But I can't seem to get my head around how I would get an output like:
Not sure if it's a dup - will delete if so, just haven't found one for this specific scenario. I have a complex list full of tuples, which contain strings and lists.
I have a list of tuples which I want to convert to a Series. I attempt to do this by converting the list to a dictionary and then to a Series:
I have a list of tuplesI want to create a new list that only has the first two fields as in:but I cannot see how to craft a list comprehension for more than one element.
I am a new self-leaner in Haskell. firstly, I want to write a function to check if two lists of tuples are equal. Each tuple has a key and value
So for example, I have a tuple:and I would want to take out only the first number 3 in that tuple so that it would look like this instead:
How to merge a tuple with the same keyand turn them intoThe most performant approach is to use a collections.defaultdict dictionary to store data as an expanding list, then convert back to tuple/list if needed:
