Python 执行cmd命令行

import subprocess


def runcmd(command, cwd, timeout=5, shell=True, cancer_warp=False):
    try:
        p = subprocess.Popen(command, bufsize=-1, shell=shell, stdout=subprocess.PIPE, stderr=subprocess.PIPE,
                             encoding="gbk", cwd=cwd)
        p.wait(5)
        returncode = p.returncode
        stdout, stderr = p.communicate()
        if cancer_warp:
            stdout = stdout.split(('\n'))
        result = {
            "returncode": returncode,
            "stdout": stdout,
            "stderr": stderr,
        }
        return result
    except Exception:
        pass

if __name__ == '__main__':
    result=CmdUtil.runcmd(command="dir", cwd="C:\",cancer_warp=True)
    print(result)

遇到的报错（改一下字符集编码就可以了）：

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc7 in position 1: invalid continuation byte
