当我们在循环外使用continue语句时,会出现 Python“SyntaxError: 'continue' not properly in loop”。 要解决该错误,请在for或while循环中使用continue语句并确保我们的代码缩进正确。 下面是一个产生上述错误的示例代码 iflen('hi') ==2:# ⛔️ SyntaxError: 'continue' no
This is the error message, telling us that thecontinuekeyword is not inside the loop body. We only receive this error message when we use thecontinuekeyword outside the loop body. In the above example, we have used thecontinuein theif..elsebody, that's why Python's parser raised the er...

上下文管理器对象存在以控制with语句,就像迭代器存在以控制for语句一样。 with语句旨在简化一些常见的try/finally用法,它保证在代码块结束后执行某些操作,即使代码块由return、异常或sys.exit()调用终止。finally子句中的代码通常释放关键资源或恢复一些临时更改的先前状态。
You'll also learn the difference between using a while loop and a for loop. Also the topic of nested loops After, you'll see how you can use the break and continue keywords. The difference between the xrange() and range() functions While Loop The while loop is one of the first loop...
