根据进程名获取进程PID的python实现

import psutil as pt

def getPidByName(Str):
    pids = pt.process_iter()
    pidList = []
    for pid in pids:
        if pid.name() == Str:
            pidList.append(pid.pid)
    return pidList


if __name__ == '__main__':
    pid = getPidByName('chrome.exe')
    print('pid is:',pid)

运行结果：

	pid is: [3592, 4552, 10268, 11068, 11096, 11632, 12672]
