Leverage enumeration: Python's built-in 'enumerate' function allows you to loop over a sequence while also having access to the index of the current item. This can be very handy in certain scenarios. In conclusion, the Python 'for' loop is a fundamental tool for iterating over sequences....
当我们在使用Python异步编程时,特别是使用asyncio库时,可能会遇到"RuntimeError: Event loop is closed"错误。这个错误通常在以下场景中发生: 在异步任务执行完毕后,再次调用asyncio.get_event_loop().run_until_complete()或asyncio.get_event_loop().run_forever()函数。 在异步任务中使用了已经关闭的事件循环。

查阅资料后发现,发现使用jupyter notebook环境,其连接着 IPython 内核,而 IPython 内核本身在事件循环上运行,而 asyncio 不允许嵌套其事件循环,因此会出现如上图的错误信息。 nest_asyncio 作为异步操作的补丁而存在,具体内容请参考:

As you can see from the output of the for loop used to print each character in a string,print()adds a new line automatically. If you just need to print just a single new line and nothing else you can simply callprint()with an empty string as its argument. Python will still insert ...
A for loop is a programming construct that allows a block of code to be executed repeatedly until a certain condition is met.
