For Windows, you could use WMI. Something like this:

code
import wmi

c = wmi.WMI ()
for i in c.Win32_ComputerSystem ():
  print i.TotalPhysicalMemory

for i in c.Win32_Processor ():
  print i.DeviceID, i.MaxClockSpeed, MHz

/code

You can get the wmi module from:

   Hello,

 Is there a module for these types of queries? platform.platform returns 
 the computer's CPU name and type, but not its frequency; nor does it 
 report how much memory the computer has. In the python help(), I 
 searched for moudles cpu, but non were found.

   Many Thanks,

For looking at memory on windows you might be able to make improvements 
to this class I wrote.  I was going to add memget() methods for getting 
individual items,  but it wasn't as useful as I was hoping it would be 
in checking my python memory use.  For that I need info on individual 
tasks, but this might be better for your use.

Cheers,
   Ron

 For Windows, you could use WMI. Something like this:

-cut-

For linux (and also for other *nix?)

something like this

  os.system(cat /proc/cpuinfo | grep cpu)
cpu family  : 6
cpu MHz : 1922.308

or:

  open(/proc/cpuinfo).readlines()
['processor\t: 0\n', 'vendor_id\t: AuthenticAMD\n'
