Task 2 - Constants and variables

Create a variable named name and assign your name to it. Then print the value of the variable.

name = "ganesh"
print(name)

Create a variable age and assign your age to it. Later, reassign the variable with a new value and print the new value.

age = 36
age = 37
print(age)

Assign the values 5, 10, and 15 to three variables a, b, and c in a single line. Print their values.

a , b , c = 5 , 10 , 15
print(a , b , c)

Swap the values of two variables x and y without using a third variable. Print their values before and after swapping.

x , y = 1 , 2
print(x , y)
x , y = 2, 1
print(x , y )

Define constants PI with appropriate values and print them.

PI = 3.14
print(PI)

Write a program that calculates the area of a circle using the constant PI and a variable radius. Print the area.

PI = 3.14
r = 5
a = pi * r * r
print(a)
79.5

Define constants for the length and width of a rectangle. Calculate and print the area.
Define a constant for π (pi) and a variable for the radius. Calculate and print the circumference of the circle.

LENGTH = 60
WIDTH = 20
a = LENGTH * WIDTH
print(a)
1200

PI = 3.14
r = 8
circumference = 2 * pi * r
circumference = 2 * PI * r
print(circumference)
50.24
