We could avoid the code repetition above.

def get_entity_count(entity):
	try:
		file_cpuinfo =
		open("/sys/devices/system/cpu/cpu0/topology/" + entity + "siblings", 'r)
		.
		.
		.
	except
		.
		.
		.

def get_hyper_thread_count():
	return get_entity_count("thread")

def get_core_sibling_count():
	return get_entity_count("core")
