I'm using Cython to make my
Python code more efficient. I have read about the Cython's function cython -a filename.pyx
to see the "typedness" of my cython code. Here is the short reference from Cython web page. My environment is Windows 7, Eclipse PyDev, Python 2.7.5 32-bit, Cython 0.20.1 32-bit, MinGW 32-bit.
Here is the report for my code:
![enter image description here](https://i.stack.imgur.com/BQpC3.png)
So does the color yellow mean efficient or non-efficient code? The more yellow it is the more....what?
Another question, I can click on the numbered rows and the following report opens (e.g. row 23):
![enter image description here](https://i.stack.imgur.com/samlq.png)
What does this mean? P.S. If you can't see the image well enough --> right click --> view image (on Windows 7) ;)
Thnx for any assistance =)
UPDATE:
In case somebody wants to try my toy code here they are:
hello.pyx
import time
cdef char say_hello_to(char name):
print("Hello %s!" % name)
cdef double f(double x) except? -2:
return x**2-x
cdef double integrate_f(double a, double b, int N) except? -2:
cdef int i
cdef double s, dx
s = 0
dx = (b-a)/N
for i in range(N):
s += f(a+i*dx)
return s * dx
cpdef p():
s = 0
for i in range(0, 1000000):
c = time.time()
integrate_f(0,100,5)
s += time.time()- c
print s
test_cython.py
import hello as hel
hel.p()
setup.py
from distutils.core import setup
from Cython.Build import cythonize
setup(
name = 'Hello world app',
ext_modules = cythonize("hello.pyx"),
)
From command line prompt I used the command (to generate C, pyd etc files):
python setup.py install build --compiler=mingw32
To generate the report I used:
cython -a hello.pyx
