More os questions

Hello All,
I would like to log some information that os.system returns.

Code: Select all

from os import system

PY_adds = ['python-setuptools', 'python-pip', 'python3-dev',
           'python3-setuptools','python-serial',
           'python3-pip','libjpeg3-dev',
           'python-numpy','python-scipy',
           'python-pandas','python3-pygame',
           'python-pygame','python-pySerial',
           'libusb-1.0-0.dev','build-essential',
           'python-dev','libjpeg-dev']

 
for X in PY_adds:
    print(X)
    print('')
    system("sudo apt-get -y install %s" % X)

if I am just using python3 then it returns:
libjpeg3-dev

Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package libjpeg3-dev
25600


Normally os.system returns 0, I would like to grab the "X" if os.system returns 25600 and log what is not loading.

Is that an error code and if I used?
try:
def ....

except 25600:
do somthing

can you not just do something like this?

Code: Select all

...
      res = system("sudo apt-get -y install {}".format(X))
      if res == 25600:
...
      elif res == 32512:
