importasyncioimporttimeimportrandom 然后,我们定义了task_A,其执行时间是随机确定的,可以从1到5秒不等。在执行结束时,如果终止条件没有满足,那么计算就会转到task_B: deftask_A(end_time, loop):print("task_A called") time.sleep(random.randint(0,5))if(loop.time() +1.0) < end_time: loop.call_l...
To create a basic blockchain class in Python, you can follow these steps. Define a Block class that represents a block in the blockchain. Each block should have the following attributes. index: the index of the block in the blockchain data: any data that the block should store timestamp...

Python also provides a special built-in function called complex() that lets you create complex numbers. You can use complex() as follows: Python >>> c = complex(2, 3) >>> c (2+3j) >>> type(c) <class 'complex'> You can use either method to create complex numbers. You can ...

Now that Python's ready to go, we should create a virtual environment to keep things organized. This way, our scraping project won't mess with other projects on our machine. Think of it as a designated sandbox for our web-scraping adventures!
