如何从python脚本执行linux命令

Question

When I use the linux shell I write module load numeca/open/61_numeca_mpi , I press enter, the program uploads the module licence, and then I write fine and press enter again. I wrote a Python script which does this.

import os

os.system("module load numeca/open/61_numeca_mpi")
os.system("fine")

It uploads the module licence but then it says

ERROR:105: Unable to locate a modulefile for 'fine'.

Any suggestions?

Answer 1

Try using the subprocess module:

import subprocess
p= subprocess.Popen(['module','load numeca/open/61_numeca_mpi"'],stdout=subprocess.PIPE,stdin=subprocess.PIPE)
p.stdin.write('fine')
p.communicate()[0]
p.stdin.close()

Answer 2

尝试在同一外壳中执行两个命令，如下所示：

os.system("module load numeca/open/61_numeca_mpi && fine")
