python中的字符串匹配不起作用

Question

import subprocess

def volumeCheck(volume_name):
    """This function will check volume name is mounted or not.
    """
volume_name = raw_input('Enter volume name:')
volumeCheck(volume_name) 

p = subprocess.Popen(['df', '-h'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
p1, err = p.communicate()
pattern = p1

new_vol = '/VolumeData/' '+ volume_name +'

if pattern.find(new_vol) != -1 :

    print 'volume mounted'

else:
    print 'volume not mounted'

new_vol = '/VolumeData/' '+ volume_name +' i think this is wrong , but how can i do this ..?

i like to search \\volumeData\\ volume_name .

Answer 1

What exactly are you going for? If I understand properly, I would probably try os.path.join , eg:

new_vol = os.path.join('/','VolumeData', volume_name)

Also, since you're not actually using the result of find , you might want to consider:

if new_vol in p1:

instead.
