While writing a program in python, you might need to end a program on several occasions after a condition is met. Without using and operator, we can only . Working of the break statement in Python . The pass is also useful in places where your code will eventually go, but has not been written yet (e.g., in stubs for example): Example: Python Jump Statements . The below code breaks when x is equal to 25. x= 1 while True: print (x) x= x + 1 if x == 25: break print ('25 is reached. When it encounters the quit () function in the system, it terminates the execution of the program completely. The following example demonstrates if, elif, and else conditions. Code: x = 10 if x > 0: print ("x is positive") Example: The last way we had a closer look at was by "raising an exception".

Enter 1 st number: 1 Enter 2 nd number: 0 Traceback (most recent call last): File "test.py", line 19, in result = (num 1 * num 2 )/ (num 0 * num 2 ) ZeroDivisionError: division by zero. . Say for example a check for a variable 'a' ? The sys.exit() function could be invoked at any moment . If and when it turns out to be False, the program will exit the loop. Less than: a < b. if condition: break time.sleep(delay) You return ret, output whether or not the program succeeds, which may be confusing.
