1

What keyword is used to define a function in Python?

a

function

b

def

c

fun

d

define

2

What does a return statement do inside a function?

a

Creates a new variable in the global scope

b

Sends a value back to the caller

c

Prints the value to the console

d

Ends the program

3

How can a function accept a variable number of positional arguments?

a

Use *args in the parameter list

b

Use a list as the only parameter

c

Use a for loop inside the function

d

Use **kwargs in the parameter list

4

What does *args capture inside a function?

a

A tuple of extra positional arguments

b

The function’s return value

c

A list of keyword arguments

d

All the function’s local variables

5

What does a function return with no value after return?

a

0

b

'' (empty string)

c

False

d

None

6

What is a lambda function in Python?

a

A small anonymous function

b

A module-level function only

c

A type of loop

d

A named class

7

How do you call a function from another module after importing it?

a

module.func()

b

func()

c

call(module)

d

import func

8

What does a default parameter value in a function signature do?

a

It creates a new module at runtime

b

It allows omitting the argument; a value is used if not provided

c

It forces the function to run twice

d

It makes the argument mandatory

9

What is the purpose of a function docstring?

a

Hide implementation details

b

Change the function’s return type

c

Document how the function should be used

d

Execute code at import time

10

What is the correct syntax to raise an exception inside a function?

a

return ValueError("msg")

b

throw ValueError("msg")

c

except ValueError("msg")

d

raise ValueError("msg")

Feedback

1

def starts a function block in Python; other options are not valid Python keywords for defining functions.

2

return passes back a value to where the function was called; other options describe different actions.

3

*args collects extra positional arguments into a tuple; **kwargs is for keyword arguments.

4

*args bundles additional positional args into a tuple; not a list or keyword args.

5

An explicit return with no value returns None in Python.

6

Lambda creates a concise, unnamed function for simple expressions.

7

Utility is accessed via the module name (or imported alias) followed by parentheses.

8

Default values provide fallback when callers omit that parameter.

9

Docstrings describe usage, inputs, and behavior for developers.

10

Python uses raise to raise exceptions; other options are invalid syntax for raising.
