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。
Method 1: Basic Iteration and Checking The simplest way to find and print prime numbers from 1 to N in Python is by using basic iteration and checking for each number’s divisibility. Let me show you an example and the complete code. ...
