标准退出请使用sys.exit(n),os._exit(n)一般用于os.fork()创建的子进程。 # Python program to explain os._exit() method# importing os moduleimportos# Create a child process# using os.fork() methodpid = os.fork()# pid greater than 0# indicates the parent processifpid >0:print("\nIn p...
在实际应用中,可以使用sys.exit("YOUR ERROR MSG")当做快捷退出程序的方式并附加一段消息 参考 # Python program to demonstrate # sys.exit() import sys age = 17 if age < 18: # exits the program sys.exit("Age less than 18") else: print("Age is not less than 18") 1. 2. 3. 4. 5....
defstop_program():print("Stopping the program...")raiseSystemExit stop_program() 1. 2. 3. 4. 5. 在上述代码中,我们定义了一个名为stop_program()的函数,该函数在被调用时打印一条消息并使用raise SystemExit停止程序的运行。 3. 使用os._exit() os._exit()是Python中用于终止进程的函数。与前面介...

The .poll() method is a basic method to check if a process is still running. If it is, then .poll() returns None. Otherwise, it’ll return the process’s exit code. Then the program uses .read1() to try and read as many bytes as are available at .stdout. Note: If you put ...
print("Inside the main function.") # Your program logic goes here. if __name__ == "__main__": main() 输出: 复制 Inside the main function. Exiting the program. Cleanup tasks can be performed here. 在上面的实现中,@atexit.register在函数定义上面提及。它将exit_handler()函数定义为退出函数...
