What is a function in Python?

• A function in Python is a class that defines object properties.

• A function in Python is a built-in method for string manipulation.

• A function in Python is a reusable block of code defined using 'def' that can take inputs and return outputs.

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

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 arguments in a function?

• Arguments are necessary for creating global variables.

• The purpose of arguments in a function is to allow the function to accept input values for processing.

• Arguments help in returning multiple outputs from a function.

• Arguments are used to define the function's name.

What is the difference between positional and keyword arguments?

• Positional arguments are ordered; keyword arguments are named.

• Positional arguments are named; keyword arguments are ordered.

• Positional arguments require types; keyword arguments do not.

• Positional arguments are optional; keyword arguments are mandatory.

How can you set default values for function arguments?

• Set default values using 'function_name(param1=default_value1):' only.

• Use 'def function_name(param1, param2):' without default values.

• Use 'def function_name(param1=default_value1, param2):' for optional parameters.

• Use syntax like 'def function_name(param1=default_value1, param2=default_value2):' to set default values.

What is the *args syntax used for in function definitions?

• *args is used to pass a variable number of arguments to a function.

• *args is a method for returning multiple values from a function.

• *args is used to define default values for function parameters.

• *args allows for keyword arguments to be passed to a function.

What does **kwargs allow you to do in a function?

• It restricts the number of arguments a function can accept.

• It enables defining default values for all function parameters.

• It allows passing a variable number of keyword arguments to a function.

• It allows passing only positional arguments to a function.

How do you return multiple values from a function?

• Use a list to store the values before returning.

• Use a dictionary to map values to keys.

• Return values as a single concatenated string.

• Use commas to separate values in the return statement.

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

• Global scope

• Block scope

• Local scope

• Static scope

How can you pass a function as an argument to another function?

• You must define the function inside the other function to use it.

• You can pass a function as an argument by using its name without parentheses.

• You can pass a function by calling it directly inside another function.

• You can only pass a function as a string to another function.
