Python重启程序 [英] Python restart program

问题描述

我制作了一个程序，最后要求您重启.

I made a program that asks you at the end for a restart.

我import os并使用了os.execl(sys.executable, sys.executable, * sys.argv) 但是什么也没发生，为什么?

I import os and used os.execl(sys.executable, sys.executable, * sys.argv) but nothing happened, why?

代码如下:

restart = input("\nDo you want to restart the program? [y/n] > ")
if str(restart) == str("y"):
    os.execl(sys.executable, sys.executable, * sys.argv) # Nothing hapens
else:
    print("\nThe program will be closed...")
    sys.exit(0)

推荐答案

import os
import sys

restart = input("\nDo you want to restart the program? [y/n] > ")

if restart == "y":
    os.execl(sys.executable, os.path.abspath(__file__), *sys.argv) 
else:
    print("\nThe programm will me closed...")
    sys.exit(0)

os.execl(路径，arg0，arg1，...)

os.execl(path, arg0, arg1, ...)

sys.executable:python可执行

sys.executable: python executeable

os.path.abspath(__file__):您正在运行的python代码文件.

os.path.abspath(__file__): the python code file you are running.

*sys.argv:剩余参数

它将再次执行程序，类似于python XX.py arg1 arg2.

It will execute the program again something like python XX.py arg1 arg2.
