運(yùn)行shell命令并捕獲輸出我想編寫一個(gè)函數(shù)，它將執(zhí)行shell命令并返回其輸出。如一串不管是錯(cuò)誤還是成功的信息。我只想得到與命令行相同的結(jié)果。什么樣的代碼示例會(huì)做這樣的事情呢？例如：def run_command(cmd):
# ??????print run_command('mysqladmin create test -uroot -pmysqladmin12')# Should output something like:# mysqladmin:
CREATE DATABASE failed; error: 'Can't create database 'test'; database exists'
