Question

I am getting info from an HP device and storing it in a variable named data.

Now, I want to extract only the values for Chassis: and Serial Number: from the output, an example of which is below (I obtain it by typing the command show module):

============================
coaza077-cor-01> show module

 Status and Counters - Module Information
  Chassis: 2900-24G J9049A         Serial Number:   SG748KI09F
  Slot  Module Description                       Serial Number
  ----- ---------------------------------------- --------------

coaza077-cor-01> exit
Do you want to log out [y/n]? y
=============================

The code below is my attempt to do this:

    sList = os.linesep.join([s for s in data.splitlines() if s])


for i in range(0,len(sList)):

    if (sList[i].lower()).find('Chassis') >= 0:
        #DEVICE PROCESSOR
        device_processor= _parse.getdata(sList[i].lower(), 'Chassis:', ' ')
        if debugging == "_HP2900" or debugging == "ALL": print "_HP2900.py", "Processor", device_processor          

    if (sList[i].lower()).find('Serial Number') >= 0:
        print 'Serial Number'
        #DEVICE SERIAL NUMBER
        device_serial= (_parse.serial_number(sList[i].lower()[len('Serial Number'):])).upper()
        if debugging == "_HP2900" or debugging == "ALL": print "_HP2900.py", "Serial", device_serial

.. however I can’t seem to get only the two values that I need. I’m new to Python, and not sure that I’m even approaching the problem correctly.

How can I get just the fields that I need?

>>> data = """
============================
coaza077-cor-01> show module

 Status and Counters - Module Information
  Chassis: 2900-24G J9049A         Serial Number:   SG748KI09F

  ----- ---------------------------------------- --------------

coaza077-cor-01> exit

=============================
"""
>>> chasis = data.split('Chassis:')[1].split('Serial')[0].strip()
>>> serial = data.split('Serial Number:')[1].split()[0].strip()
>>> 
>>> print chasis
2900-24G J9049A
>>> print serial
SG748KI09F

Update for comment:

>>> x, y = chasis.split()
>>> print x
2900-24G
>>> print y
J9049A
