In python, the sys.exit() function is used to exit the program. When the sys.exit() function is called, the Python interpreter will exit the program immediately and return a status code. Typically, a status code of 0 indicates that the program exited normally, while a non-zero status code indicates that the program exited abnormally. For example:
import sys # 正常退出程序 sys.exit(0) # 异常退出程序 sys.exit(1)
