python文件完成后如何运行另一个python文件

Question

For example, I have two python file test1.py and test2.py. At first, test1.py will run. And I want test2.py to be run when the test1.py is finished.

I want the two python files run in different shell. That means test1.py should be closed when it is finished.

All the help is appreciated! Thank you!

I want this task to be some kind of scheduler task. At 12:00 pm the test1.py is executed. And after test1.py is finished, I want to execute test2.py automatically

Answer 1

一旦第一个脚本用atexit完成，您就可以使用shutdown钩子来执行其他脚本

atexit.register(lambda: execfile('other.py')) # pass function to execute other file

Answer 2

The easiest way is going to be to do this in the shell, not using pure python. Just run python test1.py && python test2.py or python test1.py; python test2.py python test1.py; python test2.py .

The one with && won't run test2.py if test1 fails while the one using ; will run both regardless.

Answer 3

Consider there are three files. one.py is your task one, two.py is your task two and main.py is your main file which calls the other two tasks.

You can have your code something like this.

one.py

import time

class One():
    print "Before sleep one"
    time.sleep(5)
    print "After sleep one"

two.py

import time

class Two():
    print "Before sleep two"
    time.sleep(5)
    print "After sleep two"

main.py

from one import One
from two import Two

One()
Two()

Output

python main.py
Before sleep one
After sleep one
Before sleep two
After sleep two
