Pythonで簡単なShellを実行するだけの関数

'ls -l'のような複数行は非対応。

import subprocess

# shell実行して文字で返す
def res_cmd(cmd, char_code="utf-8"):
    return subprocess.Popen(
        cmd, stdout=subprocess.PIPE,
        shell=True).communicate()[0].decode(char_code)

cmd = 'echo -n "hello world"'
res = res_cmd(cmd)
print(res)
# hellow world
