Page 2 - Lesson Note - Iterative Statement

Lesson Note
Jump statements
break
break statement terminates the execution of the loop (for/ while) and the execution
resumes from the statement immediately following the body of the terminated statement.

continue
continue statement terminates the execution of a particular iteration of the loop (for/
while) and the execution resumes from the next iteration.

i=1 i=1
while (i<10): while (i<10):
i = i+1 i = i+1
if (i%4 == 0): if (i%4 == 0):
break continue
print(i, end='') print(i, end='')

Output Output
23 235679

Loop else statement

The else clause of a Python loop executes when the loop terminates normally, not when the
loop is terminating because of break statement

i=1 i=1
while (i<10): while (i<10):
i = i+1 i = i+1
if (i%4 == 0): if (i%4 == 0):
break continue
print(i, end='') print(i, end='')
else: else:
print("Loop over") print()
print("Loop over")
Output Output
23 235679
Loop over

Random Number generation in Python

Function randint() generates a random number.
Syntax: randint(lower limit, upper limit)
(returns a random number N such that lower_limit<=N<=upper_limit)

Example:
#generates a random number N, such that 10<=N<=50
import random
x = random.randint(10, 50)
print(x)
