#I will show the steps using Python2.7.13 
If you download a newer version it should work similarly.
```
cd ~
wget https://www.python.org/ftp/python/2.7.13/Python-2.7.13.tgz
tar -xzvf Python-2.7.13.tgz
cd Python-2.7.13
./configure 
make altinstall prefix=~/.local/
```
The `configure` and `make` step takes few minutes. Now python 2.7 would be present in `~/.local/bin.`
Add this to PATH. This is very important as the following steps depend on it.

```
export PATH=~/.local/bin:$PATH
python2.7  # should work fine
```
It is a good idea to add the `export` statement to `~/.bashrc` file to load at login.
You can also create a soft-link to `python2.7` so that `python` command gives you v2.7
 ```
 cd ~/.local/bin; ln -s python2.7 python
 ```


#Lets talk about installing pip
Download the get-pip.py file and install it for the current user.
It will leave `pip` and `pip2.7` executables in `~/.local/bin`.
```
cd ~
wget https://bootstrap.pypa.io/get-pip.py
python2.7 get-pip.py --user
```


#Setting up Virtualenv and Shipping to another machine
```
pip install virtualenv --user
cd ~
mkdir venv
cd venv
virtualenv -p ~/.local/bin/python2.7  e1
virtualenv --relocatable e1
## To use e1
source ~/venv/e1/bin/activate
## pip install some libraries inside the env e1
## To exit
deactivate
```

For shipping it to a different machine 
Copy `~/.local` and `~/venv/e1`. 
You will get your python and installed packages on a different machine inside env `e1`.
It is a good idea to make a tarball and scp to save some time.
