What is a variable in programming?

• A variable in programming is a special character used for formatting text

• A variable in programming is a type of function

• A variable in programming is a symbolic name given to a value that can change during the program's execution.

• A variable in programming is a fixed value that never changes

What is the scope of a variable?

• The scope of a variable is the region of code where the variable can be accessed.

• The scope of a variable is the size of the variable

• The scope of a variable is the shape of the variable

• The scope of a variable is the color of the variable

Explain the difference between local and global variables.

• Global variables are declared within a specific function or block of code

• Local variables are accessible from anywhere in the program

• Local variables are declared within a specific function or block of code and can only be accessed within that scope. Global variables, on the other hand, are declared outside of any function and can be accessed from anywhere within the program.

• Local variables can be accessed outside of the function where they are declared

What is a function in programming?

• A function in programming is a comment that explains code

• A function in programming is a loop that repeats code

• A function in programming is a block of code that performs a specific task.

• A function in programming is a variable that stores data

What is the purpose of parameters in a function?

• Parameters are used for decorative purposes in functions

• Parameters restrict the number of function calls

• Parameters are only used in advanced programming languages

• Parameters allow functions to be flexible and reusable by accepting different values during each function call.

How do you define a function in Python?

• def functionName(parameters):

• function functionName(parameters) {}

• functionName = function(parameters):

• create functionName(parameters):

What happens when a function is called before it is defined in Python?

• The Python interpreter throws a SyntaxError.

• The function call will succeed as long as the function is defined later in the script.

• The Python interpreter throws a NameError.

• The function call is ignored by the Python interpreter.

Variables or values passed to the function in its calling statement, if required.

• function

• function call

• function argument

• function parameter

the part of a function that contains the commands; the part of the function that does the actual work

• function body

• functiona call

• function name

• function argumet

An error that results when an instruction does not follow the syntax rules or grammar of the programming language.

• name error

• syntax error

• grammar error

• call
