When you profile a Python application, Visual Studio collects data for the lifetime of the process, measured in milliseconds (ms). Follow these steps to start working with the profiling features in Visual Studio: In Visual Studio, open your Python code file. Confirm the current environment for...
为了增加执行延迟，我们在调用函数之前添加time.sleep（）方法。 在执行期间，sleep（）将在此处暂停指定的秒数，之后将调用display（）函数。示例如下：import time print('Code Execution Started')def display(): print('Welcome to Guru99 Tutorials') time.sleep(5) display() print('Function Execution...
