Python進程，psutil庫

import psutil

# 判斷是否存在進程id爲pid的進程
bool = psutil.pid_exists(pid: int)

# 獲取進程id爲pid的進程
pro = psutil.Process(pid: int)

# 獲取進程名並改爲小寫
s = pro.name().lower()

# 殺死進程
pro.terminate()

# 獲取當前所有進程id和進程名
l = psutil.pids()
print(l)
for each in l:
    print("pid:{}, name:{}".format(each, psutil.Process(each).name()))
