PyCPUID reads the information available from the CPUID assembly instruction and makes it available to any Python program.
It could be used to decide on some codepath based on whether the target computer supports SSE2.
import pycpuid
if pycpuid.HAS_SSE2:
import foobar_sse2 as foobar
else:
import foobar
It is not the goal of PyCPUID to provide a full report of all CPUID information available. It's merely a way to get raw access to the machine instruction from within Python. Some functions are provided for translation to something human readable, but this is far from complete. Full details on how to interpret the raw data can be found in the application notes of Intel and AMD.

Package requires pip for installation.
pip install PyCPUID
If you're doing this on Windows you'll need to make sure you have a C++ compiler installed and properly configured.

There's not much to it, really. PyCPUID is just a bunch of module constants.
Just import the module and access the constants. The HAS_FOOBAR constants
are Boolean flags to indicate whether the feature is available. The function
features() returns a list of all the available features as strings. There
are some other functions like vendor() and brand_string() you can use to
identify the CPU.
import pycpuid print "has SSE2:", pycpuid.HAS_SSE2 print "all availabe features:", pycpuid.features() print "brand string:", pycpuid.brand_string()
