OS command via python subprocess module

[alinaveed786]

Thanks. Seems like now unzip is not working and hence chdir too.
It works only when dir /u03/21171382 and /u03/21463894 exist

#!/usr/local/bin/python3.6
import subprocess
from plumbum import local, cmd

patch = [21171382,21463894]

ORACLE_HOME = local.env['ORACLE_HOME']
path = local.env['PATH']
local.env['PATH'] = "{ohome}/bin:{ohome}/OPatch:{path}".format(ohome=ORACLE_HOME, path=local.env['PATH'])

osTyp = cmd.uname('-s').strip()

for i in patch:
    if osTyp == 'Linux':
        cmd.unzip('-o',"/u03/p{}_*.zip".format(i))
        local.cwd.chdir('/u03/{}'.format(i))
        subprocess.run('pwd', shell=True)

        #subprocess.run('opatch apply -silent', shell=True)
        print('Patch applied')

    elif osTyp == 'SunOs':
        cmd.unzip("p{}_121020_Solaris-x86-64.zip".format(i))
    else:
        print("!!\n!! unable to determine OS type !!\n!!")

Content of /u03:
