Pass a list to a function to act as multiple arguments

Question

I think  unpack  might be the wrong vocabulary here - apologies because I m sure this is a duplicate question   My question is pretty simple  in a function that expects a list of items  how can I pass a Python list item without getting an error   my list     red    blue    orange   function that needs strings  red    blue    orange     works  function that needs strings my list    breaks    Surely there must be a way to expand the list  and pass the function  red   blue   orange  on the hoof

Yes  you can use the  args  splat  syntax   function that needs strings  my list    where my list can be any iterable  Python will loop over the given object and use each element as a separate argument to the function   See the call expression documentation   There is a keyword-parameter equivalent as well  using two stars   kwargs     foo    bar    spam    ham   f   kwargs    and there is equivalent syntax for specifying catch-all arguments in a function signature   def func  args    kw         args now holds positional arguments  kw keyword arguments
