A loop that executes indefinitely.

A method to speed up code execution.

5 / 25

E) Can functools.singledispatch be used with methods in a class?

8 / 25

H) What is the purpose of the await keyword?

To pause the execution of an asynchronous function until other code is done.

10 / 25

J) Which of the following is a correct way to annotate a function that takes a string and returns an int in Python?

def func(s: str) -> int:

def func(s: 'str') -> 'int':

def func(s) -> str: int

func(s: str): int =

11 / 25

K) How can recursion lead to errors if not properly implemented?

13 / 25

M) What are type hints in Python?

Comments that specify what type a variable should be.

A way to enforce variable types at runtime.

Annotations that specify the expected type of variables and function return values.

A tool to convert Python code to statically typed code.

14 / 25

N) In the context of asyncio, what is an event loop?

A loop that repeatedly checks for and executes awaiting tasks.

A special loop construct used only in asynchronous comprehension.

A loop that prevents events from happening out of order.

An infinite loop that listens for events from an external source.

15 / 25

O) What does asyncio.gather() do?

It waits for one asynchronous task to complete.

It runs multiple asynchronous tasks sequentially.

It cancels all running asynchronous tasks.

It runs multiple asynchronous tasks concurrently.

16 / 25

P) Which of the following is true for a recursive function?

It must always return a value.

It can only call itself once per execution.

It must have a condition that stops the recursion.

It is faster than iterative solutions.

17 / 25

Q) What is the result of function overloading using functools.singledispatch when an unregistered type is passed?

A TypeError is raised automatically.

The generic function version is called.

The program crashes without an error message.

A warning is issued, but the program continues.

18 / 25

R) How does Python simulate function overloading?

Through the use of default parameters.

Using the @overload decorator.

With the functools.singledispatch decorator.

By manually checking types within the function.

19 / 25

S) What does the async keyword in Python define?

A synchronous function.

An asynchronous function.
