完成后如何重新启动python脚本

Question

I have a python script that will be running that basically collects data and inserts it into a database based on the last time the database was updated. Basically, i want this script to keep running and never stop, and to start up again after it finishes. What would be the best way to do this?

I considered using a cronjob and creating a lockfile and just have the script run every minute, but i feel like there may be a more effective way.

This script currently is written in python 2.7 on an ubuntu OS

Thanks for the help!

Answer 1

You could wrap your script in a

while True:
    ...

block, or with a bash script:

while true ; do
    yourpythonscript.py
done

Answer 2

尝试这个：

os.execv(sys.executable, [sys.executable] + sys.argv)

Answer 3

Wrap your code in a while statement:

while 1==1: #this will always happen
    yourscripthere

Answer 4

要求它自己运行，使用相同的参数，可能应该chmod +x it

os.execv(__file__, sys.argv)

Answer 5

you could also prompt your user if they would like to run the program again in a wrap.

prompt = input("would you like to run the program?")  
while prompt == "yes":  
...  
...  
prompt = input("would you like to run program again?")  

Answer 6

Use the --wait in your shell script:

#!/bin/bash

while :
do
  sleep 5
  gnome-terminal --wait -- sh -c "python3 myscript.py 'myarg1'"
done

Answer 7

while True:
    execfile("test.py")

This would keep executing test.py over and over.
