###Installing / Upgrading Python

• current support versions

First try using your package manager, else install from source

Python 2.7.6

cd ~/workbench

wget http://www.python.org/ftp/python/2.7.6/Python-2.7.6.tgz --no-check-certificate 
tar xf Python-2.7.6.tgz 
cd Python-2.7.6
./configure
make && make altinstall    
cd ../

wget https://pypi.python.org/packages/source/s/setuptools/setuptools-1.1.4.tar.gz --no-check-certificate
tar -zxvf setuptools-1.1.4.tar.gz 
cd setuptools-1.1.4
/usr/local/bin/python2.7 setup.py install
cd ../

wget http://pypi.python.org/packages/source/p/pip/pip-1.4.1.tar.gz --no-check-certificate
tar -zxvf pip-1.4.1.tar.gz
cd pip-1.4.1
/usr/local/bin/python2.7 setup.py install
cd ../

now that we have python 2.7 and pip 2.7 we can install python packages

/usr/local/bin/pip-2.7 install X (--cert=/usr/ssl/certs/localcerts) if needed

Python 3.3.3

cd ~/workbench

wget http://www.python.org/ftp/python/3.3.3/Python-3.3.3.tgz --no-check-certificate 
tar xf Python-3.3.3.tgz 
cd Python-3.3.3
./configure
make && make altinstall
cd ../

wget https://pypi.python.org/packages/source/s/setuptools/setuptools-1.1.4.tar.gz --no-check-certificate
tar -zxvf setuptools-1.1.4.tar.gz 
cd setuptools-1.1.4
/usr/local/bin/python3.3 setup.py install
cd ../

wget http://pypi.python.org/packages/source/p/pip/pip-1.4.1.tar.gz --no-check-certificate
tar -zxvf pip-1.4.1.tar.gz
cd pip-1.4.1
/usr/local/bin/python3.3 setup.py install
cd ../

now that we have python 3.3 and pip 3.3 we can install python packages

/usr/local/bin/pip-3.3 install X (--cert=/usr/ssl/certs/localcerts) if needed
