Loop Control Statements

break statement

break statement is used to break the loop on some condition.

Example

for i in range(6):
	if i is 3:
		break
	print(i,end=' ')

Output:
0 1 2

Here we have created a loop from 0 to 5. Inside loop we have given a condition that if value of i equals to 3, then break out of loop.

Remember break burst the nearest for loop within which it is contained.

continue statement

continue statement is used to skip a value.

Example

for i in range(6):
	if i is 3:
		continue
	print(i,end=' ')

Output:
0 1 2 4 5

In the code above when the value of i becomes 3, continue forces the loop to skip without further executing any instructions inside the for loop in that current itertion.

pass statement

pass is a null operator. It doesn't do anything. It acts as a placeholder when a statement is required syntactically, but no code needs to be executed.

You can use it when you are undecided what to do when certain condition occurs.

Example

for i in range(6):
	if i is 3:
		pass
	print(i,end=' ')

Output:
0 1 2 3 4 5
