how to convert ython module into deb package

I am trying to package numpy 1.12.1 into deb package. In order to do that first I run

dh_make -f ../numpy1.12.1.tar.gz

and it generates a debian directory, in the control file generated it shows numpyBROKEN, I change that to numpy1.12.1 and edit debian/rules to tell that this package has a setup.py file and must be compiled with python3. This is my debian/rules file:

#!/usr/bin/make -f
# See debhelper(7) (uncomment to enable)
# output every command that modifies files on the build system.
#DH_VERBOSE = 1

# see EXAMPLES in dpkg-buildflags(1) and read /usr/share/dpkg/*
DPKG_EXPORT_BUILDFLAGS = 1
include /usr/share/dpkg/default.mk

# see FEATURE AREAS in dpkg-buildflags(1)
#export DEB_BUILD_MAINT_OPTIONS = hardening=+all

# see ENVIRONMENT in dpkg-buildflags(1)
# package maintainers to append CFLAGS
#export DEB_CFLAGS_MAINT_APPEND  = -Wall -pedantic
# package maintainers to append LDFLAGS
#export DEB_LDFLAGS_MAINT_APPEND = -Wl,--as-needed


# main packaging script based on dh7 syntax
%:
        dh $@ --with python3 --buildsystem=pybuild

# debmake generated override targets
# This is example for Cmake (See http://bugs.debian.org/641051 )
#override_dh_auto_configure:
#       dh_auto_configure -- \
#       -DCMAKE_LIBRARY_PATH=$(DEB_HOST_MULTIARCH)

Then I run:

dpkg-buildpackage -us -uc

and it generates a package. But if I unpack the deb package or if I watch the structure folder generated by dpkg-buildpackage I only can see the following

$ ls debian/numpy1.12.1
DEBIAN  usr
$ ls debian/numpy1.12.1/DEBIAN/
control  md5sums
$ ls debian/numpy1.12.1/usr/
share
$ ls debian/numpy1.12.1/usr/share/doc/numpy1.12.1/
changelog.Debian.gz  copyright

Only the DEBIAN files and in usr folder only appear share folder nothing about the numpy compiled files...

How can I generate a debian package from python module?
