你可以使用进程的名字来的PID
pidof通过subprocess.check_output:
from subprocess import check_outputdef get_pid(name): return check_output(["pidof",name])In [5]: get_pid("java")Out[5]: '23366n'check_output(["pidof",name])将运行命令为
"pidof process_name",
如果返回码非零,则会引发CalledProcessError。
要处理多个条目并转换为整数:
from subprocess import check_outputdef get_pid(name): return map(int,check_output(["pidof",name]).split())
在[21]中:get_pid(“ chrome”)
Out[21]: [27698, 27678, 27665, 27649, 27540, 27530, 27517, 14884, 14719, 13849, 13708, 7713, 7310, 7291, 7217, 7208, 7204, 7189, 7180, 7175, 7166, 7151, 7138, 7127, 7117, 7114, 7107, 7095, 7091, 7087, 7083, 7073, 7065, 7056, 7048, 7028, 7011, 6997]
或者通过
-s标记获取单个pid:
def get_pid(name): return int(check_output(["pidof","-s",name]))In [25]: get_pid("chrome")Out[25]: 27698
