Answer 1

Another way to install python3 is using wget. Below are the steps for installation.

wget http://www.python.org/ftp/python/3.3.5/Python-3.3.5.tar.xz
tar xJf ./Python-3.3.5.tar.xz
cd ./Python-3.3.5
./configure --prefix=/opt/python3.3
make && sudo make install

Also,one can create an alias for the same using

echo 'alias py="/opt/python3.3/bin/python3.3"' >> ~/.bashrc

Now open a new terminal and type py and press Enter.
