Answer -
The following example illustrates the combination of an else statement with a for 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 тАШ%d equals %d * %dтАЩ % (num,i,j)
break
#to move to the next number, the
#first for
else:
# else part of the loop
print num, тАШis a prime numberтАЩ
When the above code is executed, it produces┬а 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
