Like other programming languages, in Python, break statement is used to terminate the loop's execution. It terminates the loop's execution and transfers the control to the statement written after the loop.If there is a loop inside another loop (nested loop), and break statement is used ...
Python break statement is used to terminate the a loop which contains the break statement. When a break statement is executed inside a loop, the program execution jumps to immidiately next statement after the loop. If the break statement is inside a nested loop (one loop inside another …...
In the above example, if i == 3: break terminates the loop when i is equal to 3. Hence, the output doesn't include values after 2. Note: We can also terminate the while loop using a break statement. break Statement with while Loop We can also terminate the while loop using the...

If we use this keyword other than, loops it will results in SyntaxError.The break keyword, incase of nested-loops, it will break the inner-loop first and the control will come to outer loop.In other words, It is used to abort the current execution of the program and control goes to ...
The 'break' statement in Python has a very specific task, which is to terminate the loop in which it is placed. Whenever the 'break' statement is encountered within a for loop or while loop, it immediately disrupts the flow and causes the loop to end. It's worth noting that the 'brea...
infinite_break.py import time start = time.time() while True: print("Processing...") time.sleep(1) if time.time() - start > 5: print("Timeout reached") break The loop runs indefinitely until 5 seconds elapse. break provides controlled exit from what would otherwise be an infinite ...
