What does this code print, and why? \(\gg \gg\) def func(a, \({ }^{* *}\) kargs): print(a, kargs) \(\gg\) func \((a=1, c=3, b=2)\)

A positional argument is a value that is passed to a function based on the order in which it appears. In our example, the function `func()` is defined to take one positional argument named `a`. When you call `func` with `a=1`, you are explicitly assigning the value `1` to the positional argument `a`.
Positional arguments are crucial as they define the first set of inputs a function can take. They are matched by position, meaning the first positional argument matches the first parameter in the function definition, the second argument matches the second parameter, and so on.
For instance, if a function is defined as `def example(x, y)`, then `example(3, 4)` assigns `3` to `x` and `4` to `y`. This makes it easy to quickly look at a function call and understand what each argument stands for, based on their order.

A keyword argument is passed to a function by explicitly mentioning the parameter name along with its corresponding value. In the `func()` function, arguments `b=2` and `c=3` are keyword arguments. These keyword arguments are captured in a dictionary called `kargs` due to the use of `**kargs` in the function definition.
Keyword arguments offer flexibility because you can specify values out of the natural order defined by the function’s parameters. This is helpful, especially in functions with many parameters. It improves readability and makes it clear which values are being passed to which parameters.
For example, in `func(a=1, c=3, b=2)`, even though `c` and `b` occur after `a`, they do not affect the position of `a` because they are explicitly named. Keyword arguments are handy when dealing with default parameter values as well, allowing you to only change the necessary ones without affecting others.

In Python, a dictionary is a collection of key-value pairs. Each key is unique and maps to a value. In our function `func()` example, the keyword arguments `b=2` and `c=3` are captured into a dictionary due to the `**kargs` syntax. When the function is called, `kargs` will be a dictionary like this: `{'c': 3, 'b': 2}`.
Dictionaries in Python are dynamic and can hold any data type for keys and values. They are highly efficient for lookups, addition, and deletion of key-value pairs. This makes them ideal for handling variables you want to access by name rather than by position.
You can create a dictionary using curly braces and specifying the key-value pairs, like so: `my_dict = {'name': 'John', 'age': 30}`. You can then access values using their keys: `my_dict['name']` would return `'John'`. Functions using `**kargs` leverage dictionaries to handle arbitrary keyword arguments effectively, making them powerful tools in Python programming.
