Day 94: Variables, Loops, and Conditionals in Python

Today, I dived into the core building blocks of Python scripting — variables, loops, and conditionals — which are essential to build logic and control flows in automation scripts.

📌 Variables

Variables let you store and reuse values in your scripts.

env = "production"
server_count = 5
print(f"Deploying to {env} with {server_count} servers")

📝 Useful in DevOps to hold environment names, IPs, credentials (via secrets), and configuration values.

---

🔁 Loops

Loops let you repeat tasks, such as configuring multiple servers or checking service statuses.

servers = ["web01", "web02", "db01"]
for s in servers:
    print(f"Configuring {s}")

📝 Great for batch operations like container cleanup, log rotation, or restarting services.

⚡ Conditionals

Conditionals allow your script to decide what to do based on certain conditions.

status = "running"
if status == "running":
    print("All systems operational.")
else:
    print("Something is wrong!")

📝 Helps in automation checks, error handling, and branching workflows.

💡 Key Takeaways

✅ Variables make your scripts dynamic and reusable
✅ Loops help scale actions across multiple servers or resources
✅ Conditionals provide decision-making logic to your scripts
