py-cpuinfo
Py-cpuinfo gets CPU info with pure Python. Py-cpuinfo should work without any extra programs or libraries, beyond what your OS provides. It does not require any compilation(C/C++, assembly, et cetera) to use. It works with Python 2 and 3.

API
get_cpu_info()
'''
Returns the CPU info by using the best source of information for your OS.
This is the recommended function for getting CPU info.
Returns None if nothing is found.
'''get_cpu_info_from_registry()
'''
Returns the CPU info gathered from the Windows Registry.
Returns None if not on Windows.
'''get_cpu_info_from_proc_cpuinfo()
'''
Returns the CPU info gathered from /proc/cpuinfo.
Returns None if /proc/cpuinfo is not found.
'''get_cpu_info_from_sysctl()
'''
Returns the CPU info gathered from sysctl.
Returns None if sysctl is not found.
'''get_cpu_info_from_kstat()
'''
Returns the CPU info gathered from isainfo and kstat.
Returns None if isainfo or kstat are not found.
'''get_cpu_info_from_dmesg()
'''
Returns the CPU info gathered from dmesg.
Returns None if dmesg is not found or does not have the desired info.
'''get_cpu_info_from_sysinfo()
'''
Returns the CPU info gathered from sysinfo.
Returns None if sysinfo is not found.
'''get_cpu_info_from_cpuid()
'''
Returns the CPU info gathered by querying the X86 cpuid register in a new process.
Returns None on non X86 cpus.
Returns None if SELinux is in enforcing mode.

These approaches are used for getting info:
- Windows Registry (Windows)
- /proc/cpuinfo (Linux)
- sysctl (OS X)
- dmesg (Unix/Linux)
- isainfo and kstat (Solaris)
- cpufreq-info (BeagleBone)
- lscpu (Unix/Linux)
- sysinfo (Haiku)
- Querying the CPUID register (Intel X86 CPUs)
Run as a script
$ python cpuinfo/cpuinfo.pyRun as a module
$ python -m cpuinfoRun as a library
import cpuinfo
info = cpuinfo.get_cpu_info()
