Jun 09, 2020 · The random.shuffle() function takes two parameters. Out of the two, random is an optional parameter. Parameters: x is any sequence you want to shuffle. x can be the list, string or tuple. The optional argument random is a function returning a random float number between 0.1 to 1.0. If not specified by default, Python uses random.random() function.
sleep() is defined in time() module of python 3.Sometimes, there is a need to hault the flow of the program so that several other executions can take place or simply due to the utility required. sleep() can come handy in such a situation which provides an accurate and flexible way to halt the flow of code for any period of time.
本篇 ShengYu 將介紹如何使用 Python 讓程式 sleep 延遲暫停時間。 time.sleep 函式會延遲暫停當前的執行緒，延遲暫停多久取決於帶入的參數， 設定單位是秒，可以接受浮點數，也就是說我想要延遲暫停 1.5 秒的話是可以的，範例如下：
Python's time library contains a predefined sleep () function. The "duration" for which we want to delay the execution is passed as an argument to the sleep () function in seconds. This function in combination with a loop serves as the Python countdown timer.
The time.sleep () function will suspend the execution for the number of seconds passed in the argument. In the above example, we are sleeping for 15 seconds in each loop iteration, which means that Python will only evaluate the exit condition of the loop at a rate of four times per minute, compared to as fast as it could in the previous version.
Python time Module. In this article, we will explore time module in detail. We will learn to use different time-related functions defined in the time module with the help of examples.
