如果子进程还需要输入，则可以通过communicate()方法输入：
import subprocess
print('$ nslookup') p = subprocess.Popen(['nslookup'], stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE) output, err = p.communicate(b'set q=mx\npython.org\nexit\n') print(output.decode('utf-8')) print('Exit code:', p.returncode)
Traceback (most recent call last): File "pt1_subprocess.py", line 27, in <module> print(output.decode('utf-8')) UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc8 in position 2: invalid continuation byte
###怎么解决呢？
window的环境下，cmd默认的字符集是gbk 把这一句 print(output.decode('utf-8')) 改成 print(output.decode('gbk')) 就行了

运行报错
