What automation means

Automation is writing code that:

• performs repetitive tasks reliably
• reduces human error
• creates repeatable workflows

Good targets:

• organizing files
• backups
• cleaning data
• generating reports

What makes a good automation script

• Idempotent when possible (safe to run twice)
• Has clear inputs/outputs
• Has logging
• Has a dry-run mode

A simple example: generate folders

from pathlib import Path
 
 
def ensure_structure(base: Path):
    for name in ["input", "output", "logs"]:
        (base / name).mkdir(parents=True, exist_ok=True)
 
 
ensure_structure(Path("./my_job"))

from pathlib import Path
 
 
def ensure_structure(base: Path):
    for name in ["input", "output", "logs"]:
        (base / name).mkdir(parents=True, exist_ok=True)
 
 
ensure_structure(Path("./my_job"))

Safety checklist

• test on a sample folder
• print actions first
• keep backups
• avoid hardcoding absolute delete paths
