  • Partial is also useful in cases when a function needs to be passed as an argument because it enables us to set its arguments beforehand.
  • A few examples being: 'defaultdict(<func>)', 'iter(<func>, to_exc)' and dataclass's 'field(default_factory=<func>)'.

Non-Local

If variable is being assigned to anywhere in the scope, it is regarded as a local variable, unless it is declared as a 'global' or a 'nonlocal'.

Unlike listdir(), scandir() returns DirEntry objects that cache isfile, isdir and on Windows also stat information, thus significantly increasing the performance of code that requires it.
