Answers Key:

Generic 3

5 x 3 = 15

Break	Continue
The break statement terminates the loop containing it.	The continue statement is used to skip the remaining part of a loop.
Control of the program flows to the statement immediately after the body ot the loop.	Control of the program flows start with next iteration
Syntax : break	Syntax : continue

Syntax :
while <condition>;
statements block 1
[else:
statements block2]

Code :
n1 = int(input(:Enter the first number:"))
n2 = int(input("Enter the second number:")
n3 = int(input(:Enter the third number:")
if(n1?=n2) and(n1>=n3) :
biggest = n1 ;
elif(n2>=nl)and (n2>=n3) :
biggest = n2
else:
biggest = n3
print("The biggest number between",n1,",",n2"and"n3"is",biggest)
Output :
Enter the first number : 1
Enter the second number : 3
Enter the third number : 5
The biggest number between 1, 3 and 5 is 5

(i) The if.. else statement provides control to check the true block as well as the false block,
(ii) Syntax :
if <condition> :
statemets-block 1
else :
statement-block 2
(iii) if..else statement thus provides possibilities and the condition determines which BLOCK is to be executed.

for i in range (1, 6) :
for j in range (65, 65 + i)
a = chr(j)
print a
print
