Python Functions Quiz

What is a function in Python?

• A block of reusable code that performs a specific task.

• A data type that stores multiple values.

• A loop that repeats instructions.

• A variable that stores a value.

How to define a function in Python?

• function_name:

• function_name(parameters):

• function_name(parameters)

• def function_name(parameters):

How do you call a function in Python?

• Use the function name followed by brackets.

• Use the function name followed by a semicolon.

• Use the function name followed by parentheses.

• Use the function name followed by a colon.

What does the return statement do in a function?

• Defines a new variable in the function.

• Terminates the function's execution.

• Prints a message on the console.

• Specifies the function's return value.

What's the difference between parameters and arguments in a function?

• They are the same.

• Parameters are passed when the function is called, arguments are defined in the function definition.

• Parameters are defined in the function definition, arguments are passed when the function is called.

• Parameters are used in built-in functions, arguments in user-defined functions.

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

• Limited to that function.

• Limited to the file it is defined in.

• Limited to the class it is defined in.

• Global.

What is a recursive function?

• A function that calls another function within its own definition.

• A function that uses loops instead of function calls.

• A function only used in object-oriented programming languages.

• A function that calls itself within its own definition.

How can you pass a variable number of arguments to a function?

• Using *args

• Using $args

• Using &args

What is a lambda function in Python?

• A built-in function in Python.

• A function used only once.

• A function that cannot take arguments.

• A small anonymous function in Python.

What's the difference between local and global variables in Python?

• Local variables are accessible only within the main function, global variables can be accessed from anywhere in the program.

• Local variables are defined within a function or code block, global variables are defined outside of any function or code block.

• Local variables have a shorter lifespan than global variables, which exist throughout the program.

• Local variables can be modified by any function, while global variables can only be modified by the main function.
