 python 自动重启本程序，直接上代码，分为两种情况，一种是类中的调用
代码如下：

import time
import sys
import os
i = 0
class forasp:
    def restart(self):
        python = sys.executable
        os.execl(python, python, *sys.argv)
    pass
if __name__ == "__main__":
    print('start...')
    i = i + 1
    print("5秒后,程序将重新启动")
    time.sleep(3)
    print(i)
    cn = forasp()
    cn.restart()

import time
import sys
import os
i = 0
def restart():
    python = sys.executable
    os.execl(python, python, *sys.argv)
if __name__ == "__main__":
    print('start...')
    i = i + 1
    print("5秒后,程序将重新启动")
    time.sleep(5)
    print(i)
    restart()
