Hi rcs1000, thank you very much! I even don't know how but I have done something similar today! I used a function and configured IFTTT webhooks with POST request. I think I'm going to do things right.
I found something wrong... I tried to run my script just for test and it gives me an error. I searched on Google and I found that PythonAnywhere blocks external sites with a proxy or something like that. I visited a page (here http://help.pythonanywhere.com/pages/RequestingWhitelistAdditions/ ) that suggested me to ask for the input of my site (made with Blogger) in their whitelist. I sent them a feedback from the top link. Hope they'll add the site.
However this is another problem xD. I think I'm going to write a post about ifTTT and PythonAnywhere and paste the link here.
Thanks for your fast reply!!
