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