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

• function_name = (parameters) => {}

• create function_name(parameters):

• def function_name(parameters):

• function function_name(parameters) {}

How do you pass parameters to a function in Python?

• You cannot pass parameters to a function in Python.

• You pass parameters to a function by defining them in the function's parentheses and calling the function with the corresponding values.

• You pass parameters by using global variables only.

• Parameters can only be passed as strings in Python.

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

• The return statement allows a function to print messages to the console.

• The return statement pauses the function until it is called again.

• The return statement allows a function to output a value and terminate its execution.

• The return statement is used to define a function's parameters.

Explain the concept of variable scope in Python functions.

• Variables in Python are always global regardless of where they are defined.

• Local variables can be accessed from any function in the module.

• Global variables can only be accessed within the function they are defined.

• In Python, variable scope determines where a variable can be accessed: local variables are accessible only within their function, while global variables can be accessed throughout the module.

What is a docstring and how is it used in a function?

• A docstring is a comment that only explains the syntax of a function.

• A docstring is a special type of return value from a function.

• A docstring is a type of variable used in a function.

• A docstring is a comment that describes a function's purpose and usage, defined as the first statement in the function.

Can a function have default parameters? If so, how?

• A function cannot have default parameters if it has variable-length arguments.

• No, default parameters can only be used in classes.

• Yes, a function can have default parameters by assigning default values in the function definition.

• Default parameters can only be used in global functions, not in local ones.

What happens if you call a function without providing the required parameters?

• The function ignores the missing parameters.

• The function returns a null value.

• The function executes with default parameters.

• An error occurs, indicating missing required parameters.

How can you return multiple values from a function?

• Return a tuple, list, or dictionary from the function.

• Return a single value only.

• Use global variables to store values.

• Print the values instead of returning them.

What is the difference between local and global variables?

• Local variables are always stored in the heap; global variables are stored in the stack.

• Local variables are scoped to a function; global variables are accessible throughout the program.

• Local variables can be accessed globally; global variables are limited to a function.

• Local variables can be modified by any function; global variables cannot be changed.

How do you access a variable defined inside a function from outside?

• Return the variable from the function or use a closure.

• Access the variable directly using its name.

• Modify the function to print the variable instead of returning it.

• Use global variables to store the function's variables.
