Break statement in python programming language
We will learn about how break statement work in python programming language. Break statement alter the flow of control of normal loops(for loop and while loop) and it is used to terminate the flow of the loop.
break statement performs based on the boolean expression.
Typically, loops iterate over the block of statements until test expression is false. but, if we want we can terminate the current iteration before the loops can complete their iteration using the break .

Example for the break in for loop
program 1
for val in range(1,10):
if val==5:
break
print val
print('End of the loop')
When the above code is compiled and executed, it will produce the following results
1 2 3 4 End of the loop
In the program when becoming vall==5 break statement executed and exit of the loop
program 2
n=input("Enter any number for n :")
sum=0 #initialized sum as zero
for i in range(1,10):
if i==n:
break #teminated loop using break
sum=sum+i
print sum
print("End of loop")
When the above code is compiled and executed, it will produce the following results
Output 1
Enter any number for n: 4
1
3
6
End of loop
Output 2
Enter any number for n: 6
1
3
6
10
15
End of loop
Example for the break in while loop
Program 1
i=1
while i<=10:
if i==5:
break
print i
i=i+1
print("End of loop")
At above program, when becoming i==5 break statement executed and control flow exit from the loop
When the above code is compiled and executed, it will produce the following results
1 2 3 4 End of loop
Program 2
n=input("Enter any number for n :")
sum=0 #initialized sum as zero
i=1
while i<=10:
if i==n:
break #terminated loop using break
sum=sum+i
print sum
i=i+1
print("End of loop")
When the above code is compiled and executed, it will produce the following results
Output 1
Enter any number for n: 4
1
3
6
End of loop
Output 2
Enter any number for n: 6
1
3
6
10
15
End of loop
Output 3
Enter any number for n: 9
1
3
6
10
15
21
28
36
End of loop
