如何在Python中全天每十分钟执行一次程序

Question

I am working on web crawler app to download the stock price every ten minutes. I am able to extract the quote but I am not sure how to schedule it to run every ten minutes for the entire day. Please suggest me either time loop kind of a thing or the solution for the web crawler app itself.
I need a solution which works on Windows.

Answer 1

you can do try this

import time

and but this code before dawnload method

time.sleep(10*60) #this will stop the program for 10 minutes

Answer 2

Use crontab. Open the crontab file via terminal:

$ crontab -e

At the end of the file you can set the python script and the frequency of running it. For example to run a script every 10 mins:

*/10 * * * * /path/to/script

Answer 3

Ok, so you have a python function f() which you want to execute every ten mins for a day. You can do this:

import time
while True: #Infinite loop
    f() #Execute the function
    time.sleep(600) #Wait 600s (10 min) before re-entering the cycle

And you keep the script running for as long as you need (a day, a week, whatever, it will not close by itself)

Answer 4

Windows has a Task Scheduler built-in. You can use that to run your script:

Otherwise, you can write an infinite loop that will check the stock prices every ten minutes using something like time.sleep(600) . Note that you can add your program to run at startup fairly easily:
