在開發過程中，經常會碰到需要設置程序優先級，這時候可以手動到任務管理器中調整，但是這多多少少有些不方便，那么這時候我們就可以通過subprocess調用wmic命令來實現，方法如下:

step 1 必要的引用:

import subprocess                           # Subprocess calling

step 2 函數封裝:

def set_priority_by_name(process_name, priority="normal"):priority_map = {"realtime": 256,         # REALTIME_PRIORITY_CLASS（實時）"high": 128,             # HIGH_PRIORITY_CLASS（高）"above_normal": 32768,   # ABOVE_NORMAL_PRIORITY_CLASS（高于正常）"normal": 32,            # NORMAL_PRIORITY_CLASS（正常）"below_normal": 16384,   # BELOW_NORMAL_PRIORITY_CLASS（低于正常）"low": 64,               # IDLE_PRIORITY_CLASS（低）}# 獲取優先級數值（默認正常）priority_value = priority_map.get(priority.lower(), 32)# 構造 wmic 命令cmd = f'wmic process where name="{process_name}" call setpriority {priority_value}'try:  # 需要管理員權限（尤其是 high/realtime）subprocess.run(cmd, check=True, shell=True, capture_output=True)except subprocess.CalledProcessError as e:print(f"speed level set failed: {e.stderr.decode().strip()}")except Exception as e:print(f"unknown error: {str(e)}")else:print(f"set {process_name}'s priority to: {priority}")#end tray#end def

step3. 調用?

set_priority_by_name("yourapp1.exe", "above_normal")    # 設為above_normal
set_priority_by_name("yourapp2.exe", "high")            # 設為high
