Answer 2

Answer: Option (a) is correct.

Concept:

A function is a code block To execute a function it is required to invoke it. Parameters are data that can be passed into a function. As a result, a function can return data.

Given:

salary = 8000                    #global variable

def printSalary():

   salary = 12000               #local variable  

   print("Salary:", salary)

printSalary()

print("Salary:", salary)

Find:

Find the output of the given code.

Solution:

Local variable:

Local variables are variables that are created within a function and are associated with a particular function. Outside of the function, it can't be accessed.

Global variable:

Global variables are variables that are defined outside of any function and are available throughout the program, that is, both inside and outside of each function.

∴ Inside the function, it will take the local variable's value (salary = 12000), and outside the function, it'll take the global variable's value (salary = 8000).

Output:

Salary: 12000

Salary: 8000
