program to input any choice and to implement the following. Choice Find 1. Area of square 2. Area of rectangle 3. Area of triangle

Selective Statements: In this program, some portion of the program is executed based upon the

conditional test. If the conditional test is true, compiler will execute some part of the program, otherwise it

will execute other part of the program. This is implemented in python using if statement.

Syntax:

if (condition): if (condition):

statements statements

else (or) elif (condition):

statements statements

else:

Statements

Example:

1. Program to find the simple interest based upon number of years. If number of years is more than 12 rate of interest is 10 otherwise 15.

Code:

p = input("Enter any principle amount")

t = input("Enter any time")

if (t>10):

si = p*t*10/100

else:

si = p*t*15/100

print "Simple Interest = ",si

output:

Enter any principle amount 3000

Enter any time12

Simple Interest = 3600

2. Write a program to input any choice and to implement the following.

Choice Find

1. Area of square

2. Area of rectangle

3. Area of triangle

Code:

c = input ("Enter any Choice")

if(c==1):

 s = input("enter any side of the square")

 a = s*s

 print"Area = ",a

elif(c==2):

 l = input("enter length")

 b = input("enter breadth")

 a = l*b

 print"Area = ",a

elif(c==3):

 x = input("enter first side of triangle")

 y = input("enter second side of triangle")

 z = input("enter third side of triangle")

 s = (x+y+z)/2

 A = ((s-x)*(s-y)*(s-z))**0.5

 print"Area=",A

else:

 print "Wrong input"

Output:

Enter any Choice2

enter length4

enter breadth6

Area = 24
