Mastering Python Functions

What is the correct syntax to define a function in Python?

• function function_name(parameters)

• def function_name(parameters):

• function_name(parameters) = def

• define function_name(parameters):

What are the different types of function arguments in Python?

• Positional arguments, keyword arguments, default arguments, variable-length arguments (*args, **kwargs), keyword-only arguments.

• Single-value arguments

• Static arguments

• Named parameters

How do you return multiple values from a function in Python?

• Use a print statement to display values directly.

• Return a single value that is a list of values.

• Use a return statement with multiple values separated by commas.

• Use global variables to store multiple values.

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

• Global scope

• Block scope

• Local scope

• Static scope

How can you modify a global variable inside a function?

• Declare the variable inside the function only.

• Use the 'local' keyword to modify it.

• Assign a new value without any keywords.

• Use the 'global' keyword to modify a global variable inside a function.

What is the purpose of exception handling in Python functions?

• The purpose of exception handling in Python functions is to manage errors gracefully and maintain control over program execution.

• To ensure that all functions return a value.

• To automatically generate documentation for functions.

• To improve the performance of Python functions.

How do you create a user-defined function in Python?

• function function_name(parameters)

  { return function body }

• def function_name(parameters): # function body

• function_name(parameters)

  => function body

• create function_name(parameters)

  { function body }

What are positional parameters in a function?

• Positional parameters are always optional in a function.

• Positional parameters are only used in object-oriented programming.

• Positional parameters are function parameters that are assigned values based on their order in the function call.

• Positional parameters can be assigned values in any order.

What is a default parameter in a function?

• A default parameter is a function parameter that has a default value assigned to it.

• A default parameter is a variable that cannot be changed.

• A default parameter is a parameter that must always be provided.

• A default parameter is a function that does not take any arguments.

Explain the flow of execution when a function is called.

• The function executes in parallel with other functions.

• The function runs without creating a new context.

• The function only returns values without executing any code.

• The flow of execution involves transferring control, creating a new context, assigning parameters, executing code, returning values, and destroying the context.
