Slow Python Script and Using Pipenv with AWS Lambda
I’m working on improving a python script I wrote to get a list of old posts from a wordpress website. Basically I want to be able to see what post I wrote X years ago on this day for any wordpress site.
This script uses the wonderful requests library and the very powerful public Wordpress API.
I am also using pipenv for the first time and its wonderful. I wish I started using this tool years ago.
What it Does Right Now
- Takes a dictionary of sites and iterates over each one
- Prints out to the console
print("1 year ago I wrote about {0} {1}".format(p['title']['rendered'], p['link']))
if years_ago > 1:
print("{0} years ago I wrote about {1} {2}".format(years_ago, p['title']['rendered'], p['link']))
The Script is Super Slow
You can time how long a script takes on OS X using thetime
command.

Plans for Optimization
- Use Redis (or something) to cache the results.
- Get rid of some of the for loops if we can.
Plans for Usage
- Deploy to AWS (Labmda?)
- Have this run on a Cron Job every day (using CloudWatch)
Plans for Additional Features
I want to share all of the posts from that day on social media. Instead of plugging in all of the various accounts that I need I am planning on using the Buffer API to post everywhere at once and queue up posts so that it does not fire off a bunch of stuff at the same time in the event that there are many posts for that day.This will involve doing some sort of Outh dance because I don’t think that Buffer offers using personal access tokens.
I'll Just Use Lambda
Famous last words.It’s not the worst thing in the world, but when you are using the amazing pipenv tool you have to go track down where the site-packages are located and zip them up in order to ship your code to AWS Lambda.
Unsurprisingly someone opened a feature request for this, but the solution in the comments works just fine.
I wrote a little bash script that is being called through a Makefile to zip up the site-packages along with the core python code in preparation to ship it off to AWS Lambda.
