following are my python, qt and sip versions
root@thura:~# python -V
Python 2.7.3
root@thura:~# qmake --version
QMake version 3.0
Using Qt version 5.0.2 in /usr/lib/i386-linux-gnu

I tried to import the PyQt5 by following by this
from PyQt5.QtWidgets import QtGui, QtCore
I got the following error
ImportError: No module named PyQt5.QtWidgets
How can I solve this error.
Updated =====================
When I tried to PyQt4, I got following error.
from PyQt4.QtCore import pyqtSlot as Slot RuntimeError: the sip module implements API v10.0 to v10.1 but the PyQt4.QtCore module requires API v8.1

After redo it again. I got the following error

this can be solved under MacOS X by installing pyqt with brew
brew install pyqt
This probably means that python doesn't know where PyQt5 is located. To check, go into the interactive terminal and type:
import sys
print sys.path
What you probably need to do is add the directory that contains the PyQt5 module to your PYTHONPATH environment variable. If you use bash, here's how:
~/.bashrcexport PYTHONPATH=/path/to/PyQt5/directory:$PYTHONPATH
where /path/to/PyQt5/directory is the path to the folder where the PyQt5 library is located.
pip install pyqt5 for python3 for ubuntu
After getting the help from @Blender, @ekhumoro and @Dan, I understand the Linux and Python more than before. Thank you. I got the an idea by @ekhumoro, it is I didn't install PyQt5 correctly. So I delete PyQt5 folder and download again. And redo everything from very start.
After redoing, I got the error as my last update at my question. So, when I search at stack, I got the following solution from here
sudo ln -s /usr/include/python2.7 /usr/local/include/python2.7
And then, I did "sudo make" and "sudo make install" step by step. After "sudo make install", I got the following error. But I ignored it and I created a simple design with qt designer. And I converted it into python file by pyuic5. Everything are going well.
install -m 755 -p /home/thura/PyQt/pyuic5 /usr/bin/
strip /usr/bin/pyuic5
strip:/usr/bin/pyuic5: File format not recognized
make: [install_pyuic5] Error 1 (ignored)
