The combination of PStuil class libraries and multi -threaded programming in Python explanation

The PSUTIL library in Python is a powerful tool for checking the use of system resources, and multi -threaded programming is a method to improve program efficiency and response.The combination of PSUTIL libraries with multi -threaded programming can better use system resources and improve the performance and efficiency of programs. The following is an example to illustrate how to use PSUTIL libraries in Python to combine with multi -threaded programming. First, let's take a look at the basic usage of the PSUTIL library.The PSUTIL class library provides a series of functions and methods to check the utilization of system resources, such as the CPU utilization rate, memory utilization, disk utilization, etc.We can use the PSUTIL library to obtain various information of the system. python import psutil # Get the CPU utilization rate cpu_usage = psutil.cpu_percent(interval=1) Print ("CPU utilization rate:", CPU_USAGE) # Get memory utilization memory_usage = psutil.virtual_memory().percent Print ("Memory utilization:", Memory_usage) # Get disk utilization rate disk_usage = psutil.disk_usage('/').percent Print ("Disk utilization:", disk_usage) In the above code, we obtained the CPU utilization, memory utilization and disk utilization by calling the function of the PSUTIL library. Next, we will introduce how to use multi -threaded programming in Python to improve the efficiency of the program. python import threading # Define a thread function def print_numbers(): for i in range(1, 6): print(i) # Create a thread object thread = threading.Thread(target=print_numbers) # thread.start() # The main thread continues to perform other operations Print ("Main thread performs other operations") # 行 thread.join() In the above code, we first define a thread function `prop_numbers ()` to print numbers from 1 to 5.Then, we used the `Threading.thread` class to create a thread object,` thread`, and passed the `prop_numbers` as the target function to the thread object.Then, we use the method of `Thread.start ()` to start the thread, and the thread will execute in the background.The main thread can continue to perform other operations without waiting for the end of the thread.Finally, we use the method of `Thread.Join ()` to wait for the thread to execute. When combined with PSUTIL libraries with multi -threaded programming, you can use the PSUTIL class library to obtain system resource utilization in one thread, and perform other operations in another thread.This can improve the efficiency and response of the program while ensuring the obtaining system resource information. Below is an instance that combines the PSUTIL class library and multi -threaded programming: python import psutil import threading # Define a function to obtain system resource information def get_system_resources(): # Get the CPU utilization rate cpu_usage = psutil.cpu_percent(interval=1) Print ("CPU utilization rate:", CPU_USAGE) # Get memory utilization memory_usage = psutil.virtual_memory().percent Print ("Memory utilization:", Memory_usage) # Get disk utilization rate disk_usage = psutil.disk_usage('/').percent Print ("Disk utilization:", disk_usage) # Define a thread function def print_numbers(): for i in range(1, 6): print(i) # Create a thread object to obtain system resource information resource_thread = threading.Thread(target=get_system_resources) # Create a thread object for performing other operations operation_thread = threading.Thread(target=print_numbers) # resource_thread.start() operation_thread.start() # 行 resource_thread.join() operation_thread.join() In the above code, we define two thread functions, one to obtain system resource information (`get_system_Resources ()`)), and one is used to print numbers (`Print_numbers ()`).Then, we used the `Threading.thread` class to create two thread objects` Resource_thread` and `Operation_thread`, and passed the corresponding functions as the target function to the thread object.Then, we use the `Thread.start ()` method to start the thread, and wait for the thread to execute through the method of `Thread.Join ()`. Through the above code, we have obtained the use of system resources in one thread, and at the same time perform other operations in another thread. This can better use system resources and improve the performance and efficiency of the program. Please note that the above code is just a simple example. In actual use, appropriate modification and expansion may need to be made according to specific needs.At the same time, in order to ensure the correctness of multi -threaded operations, problems such as thread synchronization may be considered. It is hoped that the above explanation can help you understand the examples of the combination of PSUTIL libraries and multi -threaded programming.If you have any questions, please ask at any time.
