Understanding Python Functions

What is a function in Python?

• A function in Python is a built-in method that cannot be modified.

• A function in Python is a defined block of code that performs a specific task and can take inputs and return outputs.

• A function in Python is a way to create classes and objects.

• A function in Python is a type of variable that stores data.

How do you define a function in Python?

• function_name(parameters) =>

• create function_name(parameters)

• function_name: parameters()

• def function_name(parameters):

What is the purpose of the 'return' statement in a function?

• To end the execution of a function immediately.

• The purpose of the 'return' statement is to provide a value from a function to its caller.

• To create a loop within a function.

• To define the parameters of a function.

Can a function in Python take multiple arguments?

• Only one argument is allowed in a Python function.

• Yes, a function in Python can take multiple arguments.

• No, a function in Python cannot take any arguments.

• Functions in Python can only take keyword arguments.

What is the difference between a parameter and an argument?

• A parameter is the actual value supplied to the function; an argument is a placeholder in a function definition.

• Parameters are used only in global scope, while arguments are used in local scope.

• A parameter is a placeholder in a function definition; an argument is the actual value supplied to the function.

• A parameter is a type of variable, while an argument is a function's return value.

How do you call a function in Python?

• function_name(arguments)

• call_function(arguments)

• function_name[]

• function(arguments)

What are default parameters in a function?

• Default parameters are predefined values for function arguments that are used when no value is provided.

• Default parameters are optional arguments that must always be provided.

• Default parameters are values that can only be used in class methods.

• Default parameters are values that change every time the function is called.

What is a lambda function in Python?

• A lambda function is a method for defining classes in Python.

• A lambda function is a type of loop used for iteration in Python.

• A lambda function is a built-in Python data type for storing collections.

• A lambda function is an anonymous function defined with the 'lambda' keyword, allowing for quick, inline function definitions.

How can you pass a list to a function in Python?

• You must convert the list to a string before passing it.

• Lists cannot be passed to functions in Python.

• You can only pass a list by using a global variable.

• You can pass a list to a function by using a parameter in the function definition and providing a list as an argument when calling the function.

What is the scope of a variable defined inside a function?

• Block scope limited to the nearest block.

• Local scope within the function.

• Static scope that persists after the function ends.

• Global scope accessible anywhere.
