Cython is designed as a C-extension for Python. The developers can use Cython to speed up Python code execution. Performance gains are most significant in CPU-bound programs.

Here is some cpu-intense code in python

# cat compute_it.py 
import datetime
import math


def main():
 t0 = datetime.datetime.now()
 do_math(num=30_000_000)
 dt = datetime.datetime.now() - t0
 print("Done in {:,.2f} sec".format(dt.total_seconds()))


def do_math(start=0, num=10):
	pos = start
	k_sq = 1000 * 1000
	while pos < num:
		pos += 1
		math.sqrt((pos - k_sq) * (pos - k_sq))


if __name__ == '__main__':
 main()

Took 7.39 sec
