local

var

public

Question 2

What is the purpose of using non-local variables in python?

To make variables accessible from any function.

To define variables with no data type.

To modify variables in the global scope.

To modify variables in an enclosing (non-global) scope.

Question 3

What happens if you try to modify a global variable inside a function without using the global keyword?

The variable will be deleted.

The variable will become a local variable.

The modification will affect the global variable.

It will raise an error.

Question 4

What is a local variable in python?

A variable defined outside of any function.

A variable that can be accessed from any function.

A variable defined inside a function and can only be accessed within that function.

A variable defined inside a class.

Question 5

What is a constant variable in python?

A variable that cannot be modified once it's assigned a value.

A variable with a constant data type.

A variable defined inside a function.

A variable that is accessible only from a specific module.

Question 6

Which keyword is used to define a constant variable in python?

const

constant

final

Constants are not explicitly defined in python.

Question 7

Which of the following is true about the lifetime of local and global variables?

Local variables have a longer lifetime than global variables.

Global variables have a longer lifetime than local variables.

Both local and global variables have the same lifetime.

The lifetime of a variable depends on its data type.

Question 8

What is a non-local variable in python?

A variable with no data type.

A variable that is local to a specific module.

A variable that is not accessible from other modules.

A variable that is not local to the current function's scope but it is not global.

Question 9

What is a global variable in python?

A variable defined outside of any function and can be accessed from anywhere in the script.

A variable with a global data type.

A variable defined inside a class.

What is the scope of a local variable in python?

It can be accessed from any function.

It can be accessed from the entire python script.
