If a break statement executes in first program block and terminates the loop then the else clause does not execute. In the following example, while loop calculates the sum of the integers from 0 to 9 and after completing the loop, else statement executes. x = 0; s = 0 while (x < 10...
Pythonwhileloop withbreakstatement We can use abreak statementinside awhileloop to terminate the loop immediately without checking the test condition. For example, while True: user_input = input('Enter your name: ') # terminate the loop when user enters end if user_input == 'end': print(f...

The break Statement With thebreakstatement we can stop the loop even if the while condition is true: Example Exit the loop when i is 3: i =1 whilei <6: print(i) ifi ==3: break i +=1 Try it Yourself » ADVERTISEMENT The continue Statement ...
If you come from languages like C, C++, Java, or JavaScript, then you may be wondering where Python’s do-while loop is. The bad news is that Python doesn’t have one. The good news is that you can emulate it using a while loop with a break statement.Consider the following example...
The while Loop The syntax of the while loop is very similar to the if statement, as you can see above. The while loop is not very common, but in some cases, it can be very useful. Example Suppose you are numerically calculating a model based on your data. This will typically involve...
在其他编程语言中,else 只能与 if-else 搭配使用。但 Python 允许我们在 for 循环中使用 else。只有当循环正常结束时,才可以使用 else 功能。如果循环被强制终止,解释器将忽略 else 语句,因此不会执行它。注 :当循环没有被 break 语句终止时,for/while 后面的 else 块会立即被执行。
循环内用到上次学习的if语句对所猜数字比答案大还是小。每循环一次，i值增加1一次，用于记录猜的次数。The While statement is a type of loop statement. If the condition is met, the internal instruction is executed until the condition is not met. If the condition is not met, the internal ...
