两者均需 import os
(1) os.system
# 仅仅在一个子终端运行系统命令，而不能获取命令执行后的返回信息
system(command) -> exit_status
Execute the command (a string) in a subshell.
# 如果再命令行下执行，结果直接打印出来

04 | ['dump_db_pickle.py ', |
10 | 'make_db_pickle_recs.py ', |
12 | 'peopleinteract_query.py ', |
16 | 'update_db_pickle.py ', |
2 | >>> subprocess.call (["cmd", "arg1", "arg2"],shell=True) |
获取返回和输出:
3 | for line in p.stdout.readlines(): |
(4) 使用模块commands模块
3 | ['__all__', '__builtins__', '__doc__', '__file__', '__name__', 'getoutput', 'getstatus','getstatusoutput', 'mk2arg', 'mkarg'] |
5 | 'Wed Jun 10 19:39:57 CST 2009' |
7 | >>> commands.getstatusoutput("date") |
查看源代码
打印
