Answer» The following example illustrates the combination of an else statement with a for the statement that searches for prime numbers from 10 through 20. # !/usr/bin/python for num in range(10,20): #to iterate between 10 to 20 for i in range(2,num): #to iterate on the factors of the number if num%i == 0: #to determine the first factor j=num/i #to calculate the second factor print ‘%d equals %d * %d’ % (num,i,j) break #to move to the next number, the #first for else: # else part of the loop print num, ‘is a prime number’ When the above code is executed, it produces the following result : 10 equals 25 11 is a prime number 12 equals 26 13 is a prime number 14 equals 27 15 equals 35 16 equals 28 17 is a prime number 18 equals 29 19 is a prime number

Write an example to illustrates the combination of an else statement with a for statement

Answer»

The following example illustrates the combination of an else statement with a for the statement that searches for prime numbers from 10 through 20.

# !/usr/bin/python

for num in range(10,20):

#to iterate between 10 to 20

for i in range(2,num):

#to iterate on the factors of the number

if num%i == 0:

#to determine the first factor

j=num/i

#to calculate the second factor

print ‘%d equals %d * %d’ % (num,i,j)

break

#to move to the next number, the

#first for

else:

# else part of the loop

print num, ‘is a prime number’

When the above code is executed, it produces the following result :

10 equals 2*5

11 is a prime number

12 equals 2*6

13 is a prime number

14 equals 2*7

15 equals 3*5

16 equals 2*8

17 is a prime number

18 equals 2*9

19 is a prime number
