如何判断要删除的分区是否存在

sudo fdisk -l | grep /dev/sdXn

Get-Partition -DriveLetter X | Where-Object { $_.DriveLetter -eq "X:" }

import subprocess

def check_partition_exists(partition):
    try:
        # For Linux
        result = subprocess.run(['sudo', 'fdisk', '-l'], capture_output=True, text=True)
        if partition in result.stdout:
            return True
        
        # For Windows
        result = subprocess.run(['powershell', '-Command', f'Get-Partition -DriveLetter {partition}'], capture_output=True, text=True)
        if partition in result.stdout:
            return True
        
        return False
    except Exception as e:
        print(f"Error checking partition: {e}")
        return False

# Example usage
partition_to_check = "/dev/sda1"
if check_partition_exists(partition_to_check):
    print(f"Partition {partition_to_check} exists.")
else:
    print(f"Partition {partition_to_check} does not exist.")
