How can you define a function in Python that accepts an arbitrary number of positional arguments?
Understand the Problem
The question is asking how to define a function in Python that can take an arbitrary number of positional arguments. The focus is on identifying the correct syntax to achieve this, which is a common topic in programming.
Answer
Use *args to accept an arbitrary number of positional arguments in a function.
To define a function in Python that accepts an arbitrary number of positional arguments, use the asterisk (*) before a parameter name, typically called *args.
Answer for screen readers
To define a function in Python that accepts an arbitrary number of positional arguments, use the asterisk (*) before a parameter name, typically called *args.
More Information
The *args syntax allows you to receive multiple arguments as a tuple, which is useful when the number of arguments is dynamically determined at runtime.
Tips
A common mistake is forgetting that *args captures additional positional arguments into a tuple, so you must iterate over it to access the values.
