Building and installing python3.x with python2.x in Linux

RHEL 6.x doesn't comes with python3. So if any of your project require python3 and also some of the projects need python2 then you may need those 2 version same time in your system.

Prerequisite:
gcc (C89)/g++
ld
ranlib


How:
1. Download python3.x package from https://www.python.org/downloads/release/python-343/
2. Extract it and move inside the package python-3.4.3
$ cd /python-3.4.3
3. Open a console and run the following configure command. We will build python with shared library support as many of the other project will require python3 dynamic library linking.

so, configure it by,
$ ./configure --prefix=/opt/python3 --enable-shared

We are putting build output directory as /opt/python3.

4. After completion now build it by,

$ make
 5. Then install it by alternate installation by,
$ make altinstall

6. Now create a symlink of the newly created python3 binary and copy the shared library to the /lib64/ directory of filesystem.
$ ln -s /opt/python3/bin/python3.4 /usr/bin/python3
$ cp /opt/python3/libpython3.* /lib64/
7.  Now run python script by,
 $ python3 my.py
And your python2 is also ok and usable!

    Thanks for sharing your honest experience. When I first took a look at my head shots,
    I wasn’t too thrilled with mine but you’ve given me a new perspective!

My favourite writer Humayun Ahmed

There is none who can replace him.At least the standard which he create in is life time in the running literature it never be replaceable.The new generation which is all the time busy in playing PC games,chatting ,bands etc. only his writing makes them to take a glance on the literature.For example Himu and Misir ali all the time keep them on track by anti-logic and logic.They also have show-down on the novel.I myself read all of the books of Himu and Misir ali and wait for the new one to come every year.Now I have to wait for life time. Except books he makes our dirty film industry pure by his heart warming ,well versed film.Following him many new producer try to make well and good film (not the dirty one) .He also contribute our drama by his dashing drama's. In writing except romance ,logic ,anti-logic ,he also write many science fiction.His brother Sir Dr. Md. Zafar Iqbal is the man who started science fiction in bangla. The list of books: Selected novels • Lilaboti (2...
