Parameters vs Arguments

Positional Arguments

Keyword Arguments

Exercises

*args - Variable Positional Arguments

**kwargs - Variable Keyword Arguments

Combining Parameter Types

Order must be: regular → *args → defaults → **kwargs

Unpacking Arguments

Practical Example

Key Takeaways

• Parameters: in function definition
• Arguments: values passed when calling
• Positional args: order matters
• Keyword args: name=value, order doesn't matter
• *args: variable positional arguments (tuple)
• **kwargs: variable keyword arguments (dict)
• *list unpacks list, **dict unpacks dict
