<@Adrian> and are you using this for a ChoiceField by chance? It doesn't _have_ to be a tuple I don't think, it just needs to be iterable, so `l` probably works as is

Even if it needs to end up being a tuple. It's better to keep it in an some related object until you need to raw tuple.

That way you can have it throw exceptions when you want do : a, b = item.var1, item.var2 if it tries to unpack a None or wrong object you can catch that exception to prevent an error.

Hello all. This is the very first time, I am trying something like this in Python. I need help. I am writing a script that reads from a csv file and gets only the headers and then I need to insert those headers into a table on SQL, but how do I define the datatypes ? I can only read the header names from csv and not the datatype of each column.

hey <#C07EFMZ1N|help> -ers, I’m looking at the documentation for `functools.partials` (<https://docs.python.org/3.5/library/functools.html?highlight=functools#functools.partial>) and it’s pretty late. Can someone eli5 why the example assigns `.func`, `.args` and `.keywords` attributes to the returned function?

Then later when the partial is actually called, it merges any additional args/kwargs with those stored values and calls the function
