Summary  
This chapter explains how Python functions accept positional arguments and how you can use dictionary unpacking (**kwargs) to pass arguments by name or by order.

In Python, **positional arguments** are function arguments passed to a function based on their position or order. When defining a function, you can specify the parameters it expects. When calling the function, you provide the corresponding arguments in the same order as the parameters.

```python
def function_name(argument1, argument2):
    ...
```

You used positional arguments by placing them in parentheses `()` and calling the function with arguments in the correct order.

You can also specify arguments using a **dictionary**, where each key represents the argument name and each value represents the argument value, by unpacking the dictionary when calling the function:

```python
def function_name(argument1, argument2):
    ...
    
args = {
    "argument1": value1,
    "argument2": value2
}
function_name(**args)
```

Using this type of specification allows us to specify arguments in any order.

# Function with two positional arguments
def greet(name, age):
    print(f'Hello, {name}! You are {age} years old.')

# Calling the `greet()` function using dictionary
greet(age=25, name='Alex')

# Calling the `greet()` function using ordered values
greet('Alex', 25)

This method of setting arguments is preferable because it enhances the readability and interpretability of the code.
