When it comes to automation, both PowerShell and Python offer powerful capabilities. Let’s explore their strengths and use cases through practical examples.

File System Operations

PowerShell

Get-ChildItem -Path "C:\Logs" -Filter "*.log" | 
    Where-Object { $_.LastWriteTime -lt (Get-Date).AddDays(-30) } |
    Remove-Item

Python

import os
from datetime import datetime, timedelta

log_dir = "C:/Logs"
threshold = datetime.now() - timedelta(days=30)

for file in os.listdir(log_dir):
    if file.endswith('.log'):
        path = os.path.join(log_dir, file)
        if datetime.fromtimestamp(os.path.getmtime(path)) < threshold:
            os.remove(path)

System Information

PowerShell

Get-CimInstance Win32_OperatingSystem | 
    Select-Object Caption, Version, LastBootUpTime

Python

import platform
import psutil

print(f"OS: {platform.system()} {platform.version()}")
print(f"Boot Time: {datetime.fromtimestamp(psutil.boot_time())}")

Key Differences

  1. Platform Support

    • PowerShell: Primarily Windows, though cross-platform with PowerShell Core
    • Python: Truly cross-platform with consistent behavior
  2. Integration

    • PowerShell: Deep Windows and Azure integration
    • Python: Extensive third-party library ecosystem
  3. Learning Curve

    • PowerShell: Steeper for non-Windows administrators
    • Python: Generally more intuitive syntax

When to Choose Which

Choose PowerShell when:

  • Working primarily with Windows systems
  • Automating Azure resources
  • Needing deep Windows integration

Choose Python when:

  • Requiring cross-platform compatibility
  • Building complex automation logic
  • Needing extensive third-party libraries

Both languages have their place in modern automation, and choosing between them often depends on your specific use case and environment.
