py-cpuinfo 0.1.0

Get CPU info with pure Python 2 & 3

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. Works on Linux, OS X, Windows, BSD, Solaris, Cygwin, and Haiku.

These approaches are used for getting info:

1. Windows Registry

2. /proc/cpuinfo

3. sysctl

4. dmesg

5. isainfo and psrinfo

6. Querying x86 CPUID register

Run as a script

$ python cpuinfo.py
python cpuinfo.py

Run as a library

import cpuinfo

# Have the library pick the best method for getting your CPU info
info = cpuinfo.get_cpu_info()

# Or use /proc/cpuinfo
#info = cpuinfo.get_cpu_info_from_proc_cpuinfo()

# Or use the Windows registry
#info = cpuinfo.get_cpu_info_from_registry()

# Or use sysctl
#info = cpuinfo.get_cpu_info_from_sysctl()

# Or use CPU CPUID register
#info = cpuinfo.get_cpu_info_from_cpuid()

# Print some CPU values
print('Vendor ID: {0}'.format(info['vendor_id']))
print('Brand: {0}'.format(info['brand']))
print('Hz: {0}'.format(info['hz']))
print('Raw Hz: {0}'.format(info['raw_hz']))
print('Arch: {0}'.format(info['arch']))
print('Bits: {0}'.format(info['bits']))
print('Count: {0}'.format(info['count']))
print('Flags: {0}'.format(', '.join(info['flags'])))
