I assume you’ve deployed something to production before and thought, “Why is this harder than building the app itself?” Yeah, I’ve been there. You’ve got logs everywhere, flaky servers, and the occasional 2 a.m. PagerDuty wake-up call.
Good news: Python isn’t just for web apps and data science — it’s a secret weapon for DevOps too. I’ve collected 7 Python tricks that make my deployments boringly smooth. And boring in DevOps is the best compliment you can get.
Let’s dive in.
1. Auto-Rollback Deployments (Your Safety Net)
Ever pushed code and instantly regretted it? Instead of SSH’ing into five servers like a headless chicken, let Python roll back automatically when something fails.
import subprocess
import sysdef deploy(version):
try:
print(f"Deploying version {version}...")

def rollback(version):
prev_version = str(int(version) - 1)
print(f"Rolling back to version…
